Description

The present invention relates to a device for storing a leash therein. The present invention further relates to a leash storable within the device, as well as a kit which includes both the device and the leash. The present invention also relates to methods of connecting and disconnecting the leash to and from the device. Training a dog recall method typically involves using a training leash. A training leash is typically a long and wide flexible elongate element. A training leash remains connected to the dog at all times. If not held by the owner, the training leash is left to trail on the ground. The length of the training leash allows the dog to move away from the owner, whilst part of the training leash typically remains in the vicinity of the owner. If required, the owner can rapidly regain control of the dog at any time, such as by stepping on the training leash to prevent the dog from moving further away, before shortening the leash to bring the dog closer. For normal dog walking, a regular, retractable leash can be used. A retractable leash is typically a long leash stored within a casing. The retractable leash can be dispensed from the casing when the dog moves further away from their owner. Upon the dog returning closer to the owner, the slack in the leash is taken up by a retraction mechanism inside the casing. To give the dog even more freedom to roam, the leash may be entirely disconnected from the dog. The disconnected leash is retracted into the casing. Until such time that the dog is trained and / or in the case of a dog not completely trusted off the leash in certain circumstances, a training leash may continue to be used, optionally alongside a retractable leash. Both a training leash and a retractable leash may therefore be required. This requires the owner having to obtain two leashes, which increases the expense of owning a dog. Both leashes need to be carried by the user, which is inconvenient. The risk of forgetting to bring one of the leashes is high. Due to the length of the training leash, the training leash generally gets tangled up. Untangling and coiling the training leash requires time and effort. Once the dog is trained, the training leash becomes redundant and is typically thrown away, which is wasteful. A further issue is that if a retractable leash breaks, both the leash and the casing need to be disposed of and replaced. This is environmentally unfriendly. The present invention seeks to provide a solution to these problems. According to a first aspect of the present invention, there is provided a leash-storage device for selectively storing a leash within, the device comprising: an inner chamber; a retraction mechanism provided in the inner chamber, the retraction mechanism having: a spool; a winding mechanism for rotating the spool in a winding direction; and a leash-connector having a connector body terminating at a free end portion, the leash-connector being adapted to enable a leash to be toollessly engaged with the retraction mechanism via translating part of the leash past the free end portion into engagement with the connector body and / or toollessly disengaged from the retraction mechanism via translating part of the leash past the free end portion out of engagement with the connector body. The leash-storage device enables a leash to be connected to the device to be usable as a retractable leash, and disconnected from the device so as to be usable as a training leash. The versatile leash negates the need for two distinct leashes fulfilling different purposes. Furthermore, there is no need to dispose of the leash once the dog is trained, which is environmentally friendlier. The device further enables a training leash to be stored compactly within, around a spool. Spooling the leash reduces the risk of the training leash becoming tangled. No tools are required to connect and / or disconnect the leash to the leash-storage device, such that the device is more practical, particularly when the user is out and about, walking their dog. Preferably, the device may further comprise a casing. The casing provides a protective barrier to avoid or reduce damage to the leash. If the leash is dirty, such as by being dirty, the casing also provides a protective barrier which prevents or inhibits the dirt from soiling the user’s belonging if the device is stored within the user’s bag, for instance. Beneficially, the connector body may include a boss. A boss has great structural strength. A boss is easy to manufacture. It is also easy to engage a loop with a boss. Preferably, the device may further comprise a locking cover. The locking cover may fulfil a range of functions. In particular, the locking cover may selectively prevent or inhibit rotation of the spool. The locking cover may prevent or inhibit disengagement of the leash from the leash-connector. The locking cover may provide a barrier to prevent or inhibit user access to the internal components, thereby reducing the risk of injury. The locking cover may improve the aesthetics of the device. Additionally, the locking cover may preferably include a locking body and a mechanismengagement portion extending from the locking body, the locking cover may be in-use movable between an engaged position and a disengaged position, wherein in the engaged position, the mechanism-engagement portion is engaged with the retraction mechanism to prevent or inhibit rotation of the spool in the winding direction; and wherein in the disengaged position, the mechanism-engagement portion is disengaged from the retraction mechanism to permit rotation of the spool in the winding direction. The locking cover is movable between two conditions or positions. Furthermore, the locking cover may be translatable between the engaged position and the disengaged position. Translation is a simple mechanism. The locking cover can be translated from the engaged position to the disengaged position or vice versa in a small space. Advantageously, the spool may comprise a cut-out portion adapted to receive the mechanism-engagement portion therein, such that in-use when the mechanismengagement portion may be received in the cut-out portion, the spool may be prevented from rotating at least in the winding direction. The interaction of the locking cover and the spool is simple and easy to operate. The flanges of the spool prevent or inhibit the locking cover from being accidentally moved to the engaged position when the locking cover and the cut-out portion are out of alignment. Conversely, the locking cover prevents or inhibits movement of the spool when the locking cover and the cut-out portion are aligned. The interaction of the locking cover and the spool therefore provides a synergistic effect. Optionally, the leash-storage device may further include a casing and wherein the locking cover may be connected to the casing by a hinge such that the locking body may be hingeably moveable between the engaged position and the disengaged position. Instead of or in addition to being translatable, the locking cover is pivotable. Beneficially, the locking cover may further comprise a blocking portion for blocking the locking cover in one of or either of the engaged position and the disengaged position. Optionally, the leash-storage device may further comprise an engagement portion for engaging with the blocking portion. Furthermore, the engagement portion may include a ridge. More preferably, the leash-storage device may comprise a pair of engagement portions, the blocking portion being positionable between the pair of engagement portions so as to be immobilised or restrained therebetween. The blocking portion and / or the engagement portion prevent or inhibit the locking cover from accidentally being moved from the engaged position to the disengaged position, and / or vice versa. Preferably, the device may further comprise an unwinding-locking element for preventing or inhibiting rotation of the spool in an unwinding direction, opposite the winding direction. Additionally, the unwinding-locking element may include a pawl element and the retraction mechanism may include at least one ratchet tooth, or vice-versa. The unwinding-locking element, when engaged, prevents or inhibits the leash being or being further dispensed from the device by locking the rotation of the spool in at least the unwinding direction. The user can limit the maximum distance between them and the animal, such as their dog, to prevent the animal from moving further away. Beneficially, the unwinding-locking element may further comprise a user-interactable element adapted to engage the pawl element with the at least one ratchet tooth upon interaction of the user with the user-interactable element. The user-interactable element is ergonomic. A pawl and ratchet arrangement enables rotation in one direction but prevents or inhibits rotation in the opposite direction. Preferably, the locking cover and the unwinding-locking element may be two distinct locking elements. Accidental movement of the locking element from the engaged position to the disengaged position when the leash is not connected to the device would result in the coil spring causing rapid rotation of the spool until there is no longer any biasing force exerted by the winding mechanism. Such as device would no longer be functional as the spool would no longer be tensioned, unless the user can independently rewind the coil spring. Having two distinct locking elements reduces the risk of the user error. In particular, the risk of actuating the locking element from the engaged position to the disengaged position is reduced if the locking cover is a distinct locking element compared to the unwinding-locking element. Alternatively, the locking cover and the unwinding-locking element may be the same locking element. A single locking mechanism may be easier and cheaper to manufacture. Fewer moving parts reduces the risk of structural failure and / or may reduce the size of device. Fewer materials being required reduces the environmental footprint of the product. A single locking element may, when engaged, directly or indirectly prevent or inhibit rotation of the spool in both the unwinding direction and the winding direction. The single locking element may prevent or inhibit spool rotation in both directions simultaneously. Alternatively or additionally, the user may be able to select which direction of rotation to prevent using the single locking element. The user thereby has greater choice. Preferably, the winding mechanism may include a coil spring. A coil spring may beneficially provide a constant force. A constant force may result in the retraction of the leash being at a constant or substantially constant rate. According to a second aspect of the present invention, there is provided a leash comprising a flexible elongate element having a first leash end and a second leash end, opposite the first leash end, the second leash end having a device-engagement portion adapted to be engageable with the leash-connector and retractable within the leash-storage device, preferably in accordance with the first aspect of the invention. The leash is configured to be removably connectable to the leash-storage device. Optionally the device-engagement portion may include a loop dimensioned so as to be in-use receivable around the connector body of the leash-connector and retractable within a leash-storage device. The loop may be formed of fabric and / or of the same flexible material as the flexible elongate element of the leash. A loop provides a simple but strong connection which negates the need for any additional connector part formed of a hard material, such as metal and / or plastic. Negating the requirement of any additional connector formed of a hard material presents a number of benefits. Firstly, when the leash is used as a training leash dragged on the ground, the risk of injury to the user, a further user and / or to the animal is reduced by the absence of any connector part formed of a hard material. Secondly, a hard connector part may not be able to accommodate a range of different leash-connectors whereas a loop of a flexible material may be deformed so as to engaged with a range of different leash-connectors, for example with a range of bosses of different shapes, or a leash-connector shaped as a hook. The leash having a loop can be used with a range of leash-storing devices. Thirdly, as the leash needs to be able to coil compactly around the spool, a deformable loop may be flattenable to reduce the volume of the device-engagement portion. In comparison, a connector formed of hard material may prevent or inhibit the efficient spooling of the leash around the spool. A connector of hard material may even chafe against and damage the leash. Beneficially, the leash may further comprise a removal-facilitating portion extending from the loop. The removal-facilitating portion helps the user to disengage the leash from the device. Preferably, the removal-facilitating portion may be a finger-tab. A finger-tab is small and can easily fit within the device. The finger-tab may even be deformable, such as foldable. According to a third aspect of the present invention, there is provided a kit comprising the leash-storage device, preferably in accordance with the first aspect, and a leash, preferably in accordance with the second aspect. Both a leash and a leash-storage device are provided as part of a kit. When provided as a kit, the leash and leash-storage device may be connected to or disconnected from each other. According to a fourth aspect of the present invention, there is provided a method of connecting a leash to the leash-storage device, the method comprising the steps of: a] obtaining a kit, preferably in accordance with the third aspect of the invention, wherein the leash and the leash-storage device are disconnected from each other; and b] connecting the leash to the leash-connector. The leash can be disconnected from the device so that the leash can be used as a training leash. Optionally, in a further step c], the leash may be spooled around the spool so as to be retracted in the leash-storage device. According to a fourth aspect of the present invention, there is provided a method of disconnecting a leash from the leash-storage device; the method comprising the steps of: a] obtaining a kit preferably in accordance with the third aspect of the invention, wherein the leash and the leash-storage device are connected from each other; and b] disconnecting the leash from the leash-connector. The leash can be connected to the device so that the leash can be used as a retractable leash and / or stored until further use. Optionally, in a further step c] prior to step b], the leash may be unspooled from around the spool. According to a fifth aspect of the present invention, there is provided a leash-storage device for selectively storing a leash within, the device comprising: an inner chamber; a retraction mechanism provided in the inner chamber, the retraction mechanism having: a spool; a winding mechanism for rotating the spool in a winding direction; and a leash-connector, the leash-connector being adapted to enable a leash to be toollessly engaged with the retraction mechanism via moving the leash into engagement with the leash-connector and / or toollessly disengaged from the retraction mechanism via movement of the leash out of engagement with the leash-connector. No tools are required to connect and / or disconnect the leash from the device.

Referring firstly to Figure 1, there is shown a device indicated generally at 10. Figure 1 also illustrates part of a leash 12. Together the device 10 and the leash 12 may optionally be referred to as a kit 14. The kit 14 or any part thereof is preferably formed of plastics, but any additional or alternative material, such as metal, carbon fibre, glass fibre, wood, glass, fabric, any other suitable material, or any combination thereof may be envisioned. Figure 2 illustrates an exploded view of the device 10 and the leash 12 for clarity. The leash 12, also referred to as a lead, in-use enables a user to retain and / or regain control of an animal by restraining it. The animal is preferably a dog. However, the animal could be a cat or any other animal that needs to be restrained. The leash 12 may even be used with a human, such as a toddler. The term “leash” is used interchangeably with the term “lead” hereinafter and throughout. The leash 12 includes a flexible elongate element 16, a device-engagement portion 18, a connector, a removal-facilitating portion 20, but any of the above may be omitted and / or a plurality of the above may be provided. The connector is not shown in the Figures. Optionally, part of the leash 12 may include a reflective element. For instance, the webbing of the flexible elongate element 16 may include a reflective trim sewn into it. The flexible elongate element 16 has a length L, width W and thickness T. The length L, width W and thickness T are indicated in Figure 1 by double headed dashed arrows. The opposite ends of the flexible elongate element 16 are referred to as first leash end 16a and second leash end 16b, for clarity. The maximum length L is preferably between 2 meters and 30 metres, but any length outside of this range may be envisioned. More preferably, the maximum length L is between 4 and 15 metres, and more preferably yet, between 8 and 15 metres. In the illustrated embodiment, the maximum length is 8 metres or thereabouts. When the leash 12 is at least partly retracted within the device 10, the length L is less than the maximum length. Preferably, the width W is greater than the thickness T. In other words, the flexible elongate element 16 is preferably a strip. The width provides greater strength to the leash 12 whilst the thinness enables compact packing of the leash 12 within the device 10. The first leash end 16a is connectable, directly or indirectly with the animal. For example, the first leash end 16a may be looped around the neck of the animal. More preferably, the leash 12 further includes the said connector at or adjacent the first leash end 16a, the connector being engageable with a collar or harness. The connector may include a clamp or clip, and more preferably a spring loaded clip, by way of example. The second leash end 16b is opposite the first leash end 16a. The second leash end 16b is connectable to the device 10. More preferably, the device-engagement portion 18 is preferably associated with the second leash end 16b. The device-engagement portion 18 in-use enables the leash 12 to be connected to and / or disconnected from the device 10. The device-engagement portion 18 is preferably at or adjacent the terminal portion of the second leash end 16b. In the shown embodiment, the device-engagement portion 18 includes a loop 18a. The removal-facilitating portion 20 in-use facilitates the grasping of and disengagement of device-engagement portion 18 from the device 10. Preferably, the removal-facilitating portion 20 is associated with the device-engagement portion 18, which includes a loop in the preferred embodiment. The removal-facilitating portion 20 preferably extends from at or adjacent the loop 18a. As illustrated, the removal-facilitating portion 20 is a finger-tab or strip, such as a strip of fabric. In Figure 1, part of the leash 12 is shown extending from the device 10. Furthermore, the leash 12 may be at least partly received or at least partly receivable within the device 10. The leash 12 may also be full removed from the device 10. The device 10 in-use enables storage of the leash 12 therein when required. The device 10 may thus be referred to as a leash-storage device 10. The device 10 includes a casing 22, an inner chamber 24, an engagement portion 26, a retraction mechanism 28, a locking cover 30, and an unwinding-locking element 32, but any of the above may be omitted and / or a plurality of any of the above may be provided. The casing 22 in-use provides a protective housing for receiving at least some of the components of the device 10 within or partly within. The casing 22 is preferably at least in part formed of a rigid or hard material. The casing 22 may be formed as a monobloc but preferably is non-monobloc. In the illustrated embodiment, the casing 22 comprises a casing body 22a and a casing plate 22b, but either may be omitted and / or a plurality of either may be provided. The casing 22, and more preferably, the casing body 22a defines the at least one said inner chamber 24. The inner chamber 24 may be referred to as the primary chamber 24a. The casing 22, and more preferably, the casing body 22a, may optionally be shaped to provide a handle. The casing body 22a may be formed from a plurality of casing sub-portions 22a’ which together form the casing body 22a. Here, the casing body 22a may be formed of two casing sub-portions 22a’ which are connected or connectable together. The casing 22 has a leashaperture 34. The leash-aperture 34 provides an access to the primary chamber. When the leash 12 is at least partly received within the device 10, the leash 12 may extend out of the device 10 through the leash-aperture 34. Optionally, the casing 22 may further comprise a leash-cleaning portion or element, not shown. The leash-cleaning portion may remove debris from the leash 12 as it is retracted into the device 10. An example of a leash-cleaning portion may be provided in the form of one or more wipers, bristles or a brush, any suitable cleaning mechanism, and any combination thereof. The leash-cleaning portion or portions may be provided at or adjacent the leash-aperture 34. The one or more wipers and / or brushes may be provided on either or both sides of the leash-aperture 34. This may enable cleaning of both sides of the leash 12. Wipers may remove liquid, such as rain water or mud from the leash 12 as it enters the casing 22. Bristles may remove debris and / or vegetation. Furthermore, the casing body 22a and the casing plate 22b may together form a further said inner chamber 24, referred to for clarity as a secondary chamber 24b. The secondary chamber 24b in-use may receive at least part of the locking cover 30 therein. The secondary chamber 24b may provide a guiding mechanism for the locking cover 30. Optionally, tracks may be provided or formed in the casing 22, such as in the casing body 22a, in the casing plate 22b and / or by the interaction of the casing body 22a and the casing plate 22b. The locking cover 30 may be movable along the tracks. The casing 22 and more preferably, the casing body 22a further includes at least one, and more preferably a plurality of said engagement portions 26. The or each engagement portion 26 in-use may interact with or engage with the locking cover 30, as will be described in more detail hereinafter. The, each or at least one said engagement portion 26 includes a protrusion, such as a ridge or pip in the preferred embodiment. The engagement portion may be referred to as a “bump stop”. A recess could easily be envisioned instead. Preferably, at least two said ridges are parallel to each other. As best shown in Figure 2, there are preferably three engagement portions 26. The engagement portions 26 may be referred to as first engagement portion 26a, second engagement portion 26b and third engagement portion 26c for clarity. The second engagement portion 26b is preferably intermediate between the first engagement portion 26a and third engagement portion 26c. Optionally, further engagement portions may be provided. Preferably, the distances between pairs of engagement portions 26 is non equal, but equal may be envisioned. In the illustrated embodiment, the distance between the first engagement portion 26a and the second engagement portion 26b is preferably smaller than the distance between the second engagement portion 26b and the third engagement portion 26c. Optionally, the first engagement portion 26a may have a greater height than one or more of: the second engagement portion 26b and the third engagement portion 26c. The retraction mechanism 28 in-use enables retraction of the leash 12 within the device 10. The retraction mechanism 28 is preferably provided at least partly, and more preferably fully within the inner chamber 24. The retraction mechanism includes a spool 36, a winding mechanism 38, a cap 40, and a leash-connector 42, but any of the above may be omitted and / or a plurality of any of the above may be provided. The spool 36, also referred to as a drum, in-use enables the leash 12 to be wound therearound. Winding the leash 12 around the spool 36 increases the compactness of the leash 12 and / or prevents or inhibit tangling of the leash 12. The spool 36 is rotatable. The spool 36 can be rotated in a rotational direction that results in the leash 12 being wound therearound, referred to as the winding direction. The spool 36 can also be rotated in a rotation direction in the opposite direction to the winding direction, referred to as an unwinding direction. Rotating the spool 36 in the unwinding direction results in the leash 12 being unspooled and dispensed from the device 10. The winding direction is one of clockwise and counterclockwise. The unwinding direction is the other of clockwise and counterclockwise. In the illustrated embodiment, the winding direction is clockwise, and the unwinding direction is counterclockwise, but the opposite arrangement could just as easily be envisioned. Preferably, the spool 36 is formed of plastics but this is optional. The spool 36 includes a cylindrical core or barrel 36a, and two flanges 36b extending from the barrel 36a. The barrel 36a is preferably hollow. Preferably, the casing 22 includes a post 44. The post 44 extends through the spool 36. The post 44 in-use functions as an axle. The axle defines a rotation axis around which the spool 36 is rotatable. Each flange 36b is or is generally circular in shape. Each flange 36b has an outward-facing surface 36bi and an inward-facing surface 36bii. The inward-facing surface 36bii faces the other flange 36b. The outward-facing surface 36bi and the inward-facing surface 36bii meet at a rim or outer perimeter 36biii. The leash 12 is windable around the barrel 36a between the two flanges 36b. The spool 36 further includes an optional spool cut-out portion 36c but the spool cut-out portion may be omitted and / or a plurality of spool cut-out portions may be provided. The or each spool cut-out portion 36c is a recess. The recess extends at least in part radially inwardly from the outer perimeter 36biii of at least one of the flanges 36b. Preferably, the or each spool cut-out portion 36c extends from the outer perimeter 36biii of a flange 36b to or towards the barrel 36a. The spool cut-out portion 36c in-use interacts with the locking cover 30 as will be described hereinafter in more detail. Optionally, the casing plate 22b may preferably have a casing spool cut-out portion 46 similar or identical to the spool cut-out portion 36c of the spool 36. The winding mechanism 38 in-use provides a biasing force to rotate the spool 36 in a winding direction and / or to prevent or inhibit the spool 36 from rotating in the unwinding direction. The winding mechanism 38 may be referred to as means for rotating the spool 36. The winding mechanism 38 is preferably positioned or positionable inside of the hollow barrel 36a. In the illustrated embodiment, the winding mechanism 38 includes a spring and more preferably, a coil spring. The coil spring is preferably an extension coil spring but a compression coil spring is an option. The coil spring is connected or connectable at one end to the spool 36 and more preferably the barrel 36a thereof. At the other end, the coil spring is preferably connected or connectable to the post 44. The cap 40 may provide a protective barrier. The cap 40 may be provided in the shape of a plate. The cap 40 may be positioned or positionable to prevent or inhibit access to the coil spring. The leash-connector 42 in-use enables the leash 12 to be connected or connectable and / or disconnected or disconnectable from the device 10. The leash-connector 42 has a connector body 48 terminating at a free end portion 48a. The connector body 48 may take any suitable shape. For example, the connector body may be provided in the shape of a hook, with the free end portion being the tip of the hook. Preferably however, the connector body 48 includes a boss. The boss is integrally formed with, connected or connectable to one of the flanges 36b and extends, preferably perpendicularly or generally perpendicularly to the said flange 36b. The boss may extend towards the other flange 36b. More preferably, the boss extends towards the spool cut-out portion 36c in the flange 36b in the shown embodiment. The boss is preferably a metal boss in the illustrated embodiment but non-metal may be envisioned, such as plastics in addition to or instead of metal. The boss may be moulded or over moulded with the spool 36, or integrally formed therewith. The boss is preferably a curved plate but a non-curved plate may be envisioned. For example, the boss may be a flat or planar plate, or a cylinder by way of examples. The loop 18a of the leash 12 is dimensioned so as to engageable with the connector body 48. More preferably, the loop 18a is in-use receivable around the connector body 48 of the leash-connector 42. This enables the connector body 48 to in use pull the leash 12 into the device 10 and wind the leash 12 around the spool 36 when the spool 36 is rotated in the winding direction. Preferably, no tools are required to connect and / or disconnect the leash 12 and leashconnector 42. In other words, the engagement and / or disengagement of the leash 12 with the leash-connector 42 is tool less. Thus, the leash-connector 42 is adapted to enable a leash 12 to be toollessly engaged with the retraction mechanism 28 via moving the leash 12 into engagement with the leash-connector 42. Additionally or alternatively, the leash-connector 42 is adapted to enable a leash 12 to be toollessly disengaged from the retraction mechanism via movement of the leash out of engagement with the leash-connector 42. In the illustrated embodiment, this is done via translating part of the leash 12 past the free end portion 48a into engagement with the connector body 48 and / or toollessly disengaged from the retraction mechanism 28 via translating part of the leash 12 past the free end portion 48a out of engagement with the connector body 48. In other words, the loop 18a of the leash 12 can simply be translated or slipped over the free end portion 48a and translated or slid into place around the connector body 48 to engage the leash 12 with the leash-connector 42. The reverse actions may be taken to disengage the leash 12 from the leash-connector 42. A close-up, underside view of the locking cover 30 is illustrated in Figure 3. The locking cover 30 in-use has at least one, and more preferably a plurality of functions, although any of the functions may be omitted. In no particular order, a first function of the locking cover 30 is to cover the leash-connector 42 and more preferably the boss. Thus, the locking cover 30 prevents or inhibits the leash 12 from accidentally becoming disengaged from the leash-connector 42. The locking cover 30 may also prevent or inhibit access to the leash-connector 42. When the locking cover 30 covers the leash-connector 42, the user cannot access the leash-connector 42 and / or internal components of the device 10. The risk of injury is reduced. Mud, grass, stones, and other debris are also prevented or inhibited by the locking cover 30 from entering the device 10. A second function of the locking cover 30 is to improve the aesthetics of the locking cover 30 by obscuring from view the internal components of the device 10. A third function of the locking cover 30 is to selectively prevent or inhibit rotation of the spool 36. In other words, the locking cover 30 may selectively lock the spool 36. The locking cover 30 includes a locking body 50a, a mechanism-engagement portion 50b and a blocking portion 50c, but any of the above may be omitted and / or a plurality of any of the above may be provided. The locking cover 30 is in-use movable between an engaged position and a disengaged position. In the first embodiment, the locking cover 30 is movable by being is translatable between the engaged position and the disengaged position. More preferably, the locking cover 30 or at least part thereof is translatable within the secondary chamber 24b between the engaged position and the disengaged position. When in the engaged position, the mechanism-engagement portion 50b is engaged with the retraction mechanism 28 to prevent or inhibit rotation of the spool 36 in at least the winding direction, and optionally in both the winding direction and the unwinding direction. The engaged position may also be referred to as a locking position, or a locked or locking condition. When in the disengaged position, the mechanism-engagement portion 50b is disengaged from the retraction mechanism 28 to permit rotation of the spool 36 in at least the winding direction, and preferably in both the winding direction and the unwinding direction. The locking body 50a in-use provides a support for the mechanism-engagement portion 50b and / or the blocking portion 50c, preferably both. In the first embodiment, the locking body 50a extends in or substantially in a plane such that the locking body 50a is or is generally planar but this is not critical. Preferably, the locking body 50a is or is generally elongate. The mechanism-engagement portion 50b in-use interacts with the spool 36, preferably by being moved into and out of the spool cut-out portion 36c. In the illustrated embodiment, the mechanism-engagement portion 50b is an abutment element or abutment flange but any alternative suitable shape or form may be envisioned. The mechanism-engagement portion 50b extends from the locking body 50a. The mechanism-engagement portion 50b extends in a direction which is non-coplanar with the plane of the locking body 50a. More preferably, the mechanism-engagement portion 50b extends or extends generally in a direction at an angle relative to the plane of the locking body 50a. The angle may be between 1° and 179°, more preferably between 20° and 120°, and even more preferably between 30° and 100° . Most preferably, the angle is between 45° and 90°. The blocking portion 50c in-use engages with or interacts with at least one said engagement portion 26 to block, immobilise or restrict the movement the locking cover 30 in one or both of the engaged position and the disengaged position. The blocking portion 50c may include a flex tab or lip 50c’ that extends from the locking body 50a, preferably from the same surface as the mechanism-engagement portion 50b. The lip 50c’ extends from the locking body 50a in a direction at an angle relative to the plane of the locking body 50a. The angle may be between 1° and 179°, more preferably between 20° and 120°, and even more preferably between 30° and 110°. Most preferably, the angle is between 40° and 100° and is here 90°. Optionally, the lip 50c’ may be part of a T-shaped protrusion, as shown most clearly in Figure 3. The blocking portion 50c interacts with the engagement portion 26 to prevent or inhibit accidental movement of the locking cover 30 relative to the casing 22. If there is a pair of engagement portions 26 in close proximity to each other, such as first engagement portion 26a and second engagement portion 26b, the blocking portion 50c may be positionable between the pair of engagement portions 26 in close proximity to each other so as to be immobilised by the pair of engagement portions 26. Here, the lip 50c’ has a thickness and the ridges are spaced apart by a distance substantially equal to the thickness of the lip 50c’. This enables the lip 50c’ to be received between, and optionally abut against both ridges simultaneously. There may be a plurality of lips 50c’. Although not provided in the shown embodiment, the locking cover 30 may optionally further comprise a user-engagement portion for increasing the ease of actuating the locking cover 30 between the engaged position and the disengaged condition. A strip of fabric, a tab, a hard protrusion, and / or a pull-ring may be examples of suitable user-engagement portions. The unwinding-locking element 32 in-use selectively prevents or inhibits rotation of the spool 36 in at least the unwinding direction, and optionally both the unwinding direction and the winding direction. The unwinding-locking element 32 includes a locking mechanism 52 and a user-interactable element 54 but either may be omitted and / or a plurality of any of the above may be provided. The locking mechanism 52 in the shown embodiment includes a pawl or pawl element 52a and at least one ratchet tooth 52b. Preferably, the at least one ratchet tooth 52b are associated with the retraction mechanism pawl element 52a and the pawl element 52a is associated with the user-interactable element 54, but the opposite arrangement may just as easily be envisioned. In the illustrated embodiment, the at least one ratchet tooth 52b is associated with the spool 36, more preferably with one or both flanges 36b. The ratchet teeth 52b may be at or adjacent the outer perimeter 36biii of the flange or flanges 36b. The ratchet teeth 52b may be provided on the inward-facing surface 36bii and / or, preferably, on the outward-facing surface 36bi of one or both flanges 36b. The tip of each tooth 52b is preferably at or adjacent to the outer perimeter 36biii. The ratchet teeth 52b extend radially outwardly. In the illustrated embodiment, one or each flange 36b has six ratchet teeth 52b as illustrated. However, any number of teeth may be envisioned. The user-interactable element 54 in-use enables the user to interact with, actuate, activate or engage the unwinding-locking element 32 for preventing or inhibiting rotation of the spool 36 in the unwinding direction. The user-interactable element 54 has a user-interactable body 54a. The pawl element 52a extends from the user-interactable body 54a, preferably in a radial or substantially radial direction. The pawl element 52a may extend coplanarly with or in a plane parallel with the or a said flange 36b. The user-interactable element 54 is thus adapted to engage the pawl element 52a with the at least one ratchet tooth 52b upon interaction by the user, such as the user’s thumb, with the user-interactable element 54. In the first embodiment, the unwinding-locking element 32 includes a plurality of pawl elements 52a. Each pawl element 52a engages with a set of ratchet teeth 52b on each flange 36b. The pawl elements 52a are preferably parallel with each other. The pawl elements 52a are spaced apart from each other. The distance between the pawl elements 52a preferably matches or matches substantially the height of the barrel 36a along the axial extent. This enables both pawl elements 52a to engage the sets of ratchet teeth 52b simultaneously. Optionally, the user-interactable element 54 and / or unwinding-locking element 32 may be biased into either the engaged condition or into the disengaged condition. For example, a biasing element or biasor, not shown, may bias the or each pawl element 52a into being disengaged from the ratchet teeth 52b and / or the user-interactable element 54 to extend outwardly of the casing 22. An example of a biasor may include a spring. The engaged condition may also be referred to as the locked or locking condition, or the engaged position. The disengaged condition may also be referred to as an unlocked condition or a disengaged position. In-use, the user wanting to take an animal such as a dog for a walk, obtains a kit 14. There may be a plurality of leashes 12 from which the user may select a leash 12. Similarly, there may be a plurality of devices 10 from which the user may select a device 10. For example, the leashes 12 and / or devices 10 may have different visual appearances such that the user can be customise the appearance of the kit 14. The device 10 and the leash 12 may already be connected to each other, as shown in Figure 4. The leash 12 extends at least in part from the device 10. The user may connect the first leash end 16a to the dog. If the casing 22 provides a handle, the user may hold the handle in their hand. The user goes for a walk with the dog, holding the casing 22 with their hand and their dog being connected to the first leash end 16a. When the unwinding-locking element 32 is disengaged, as shown in Figures 4 and 5, the spool 36 is free to rotate in the unwinding direction, as indicated by Arrow C. The leash 12 may be freely dispensed out of the casing 22, enabling the dog to increase the distance between the dog and the user. When the maximum extent of leash 12 has been dispensed, the distance between the dog and the user may no longer be increased whilst the leash 12 is connected to the device 10 held by the user. When the dog moves towards the user, the distance between them decreases. If a winding mechanism 38 is provided, the winding mechanism 38 may automatically rotate the spool 36 in the winding direction when there is some slack in the leash 12. This results in the leash 12 being automatically retracted within the device 10 and wound around the spool 36. By automatically retracting and spooling the leash 12, the risk of the leash 12 becoming tangled is decreased. To prevent or inhibit the dog moving away beyond a certain distance from the user, the user can simply engage or actuate the unwinding-locking element 32 from an unlocked condition into a locking condition. In the first embodiment, this involves depressing the user-interactable element 54 as indicated by Arrow D in Figure 5. The or each pawl element 52a is pushed into engagement with the at least one ratchet tooth 52b as shown in Figure 6. The engagement of the pawl element 52a and a said ratchet tooth 52b prevents or inhibits the spool 36 from rotating at least in the unwinding direction. As a pawl element 52a and ratchet teeth 52b are provided, the pawl element 52a may move up along the ratchet teeth 52b to permit the spool 36 to rotate in the winding direction. Thus, in all cases, any slack in the leash 12 may be taken up by retracting the leash 12 in the device 10, regardless of whether the unwinding-locking element 32 is in a locking condition or in an unlocked condition. When the user wishes to use the leash 12 as a training leash 12, the user needs to disconnect the leash 12 connected to the device 10. If the leash 12 is wrapped around the spool 36 as shown in Figure 7, the leash is unwound from around the spool 36. This may involve the user pulling out the leash 12 via the leash-aperture 34. In Figures 7 and 8, the spool 36 is illustrated as partially translucent in order to show the leash 12 wrapped around the barrel 36a. In Figure 7, the winding mechanism 38, which is preferably a coil spring, is not shown, for clarity. The leash 12 needs to be pulled until fully unspooled so that no part of the leash 12 encircles the barrel 36a, as shown in Figure 8. The winding mechanism 38, here a coil spring, applies a biasing force to the spool 36. Upon disengagement of the leash 12 from the device 10, in the absence of any other controlling factor, the winding mechanism 38 would cause the spool 36 to rotate uncontrollably, which would risk injuring the user. Additionally, the spool 36 would rotate until the winding mechanism 38 no longer applies any biasing force. In other words, the spring would lose all tension. Thus, when the user wishes to store the leash 12 within the device 10, no retraction would occur. The above problems are solved by providing a locking mechanism to prevent or inhibit the spool 36 from rotating, directly or indirectly. The locking mechanism may act directly upon the spool 36 and / or may act upon the winding mechanism 38 to indirectly block rotation of the spool. In the first embodiment, the locking mechanism is the locking cover 30. Figure 9 is a cut-away representation through part of the device 10, illustrating the locking cover 30 in the disengaged position, with parts of the device 10 and the leash 12 omitted for clarity. Figure 9 also illustrates how the blocking portion 50c of the locking cover 30, which includes a lip 50c’, abuts against the first engagement portion 26a, here a ridge, to prevent or inhibit the locking cover 30 being removed from the device 10 altogether. The user moves the locking cover 30 into the engaged position. In the first embodiment, the user translates the locking cover 30 into the engaged position, as shown in Figure 10. The locking cover 30 is preferably inserted into or inserted further into the secondary chamber 24b. The user may need to exert a small force to force the blocking portion 50c over the second engagement portion 26b and / or the third engagement portion 26c. The blocking portion 50c of the locking cover 30 may optionally engage with at least one of the engagement portions 26. This interaction between the blocking portion 50c and the engagement portion 26, preferably the third engagement portion 26c, may beneficially prevent or inhibit the locking cover 30 from accidentally moving to the disengaged condition. Preferably, the locking cover 30 remains in the engaged condition until the or a further leash 12 is reconnected to the device 10. As previously mentioned, the spool 36 comprises a spool cut-out portion 36c adapted to receive the mechanism-engagement portion 50b of the locking cover 30 therein. Moving the locking cover 30 causes the mechanism-engagement portion 50b to be received in the spool cut-out portion 36c. Under the biasing force of the winding mechanism 38, the spool 36 attempts to rotate but the edge of the spool cut-out portion 36c abuts against the mechanism-engagement portion 50b. The spool 36 is thus inhibited or prevented by the mechanism-engagement portion 50b from rotating at least in the winding direction, and preferably in both the winding direction and the unwinding direction. The locking cover 30, when moved into the engaged position, uncovers the leash-connector 42. The user may thus access the leash-connector 42 to disengage the leash 12 from the device 10, and more preferably from the retraction mechanism 28, and even more preferably from the leash-connector 42 thereof. In the first embodiment, to disengage the leash 12 from the leash-connector 42, the user moves the leash 12 out of engagement with the connector body 48, preferably by translating part of the leash 12 past the free end portion 48a. Optionally, if a removal-facilitating portion 20 is provided, such as a tab or strip of fabric, the user can grasp the removal-facilitating portion 20 and pull the leash 12 out of engagement. Figure 11 and the close-up of Figure 12, illustrate the leash 12 having just been disengaged from the leash-connector 42, here by translating the leash 12 upwards in Figures 11 and 12, as indicated by Arrow E. No tools are required to disconnect the leash 12, such as a screw driver or scissors. Thus, disconnection of the leash 12 from the device 10 is done toollessly. Thus, there is provided a method of disconnecting a leash 12 from the leash-storage device 10, the method including the steps of: a] obtaining a kit 14, wherein the leash 12 and the leash-storage device 10 are connected from each other; and b] disconnecting the leash 12 from the leash-connector 42. To function as a training leash 12, the leash 12 is left attached by the first leash end 16a to the animal whilst the rest of the leash 12 can trail on the ground. The animal is free to move a distance from the user, who can nevertheless quickly regain control of the animal if needed, such as by stepping on the leash 12 on the ground. The absence of any metal or plastics or hard material device-engagement portion at the second leash end 16b reduces the risk of injury to the animal and / or one or more users. When the user wishes to store the or a further leash 12 in the device 10, some of the above steps are taken in reverse to connect the disconnected leash 12 to the device 10. In particular, the leash 12 is engaged with the retraction mechanism 28, and more preferably the leash-connector 42 thereof. Preferably, this involves moving and more preferably translating part of the leash 12 past the free end portion 48a into engagement with the connector body 48. If the leash 12 has a loop 18a, the loop 18a is made to encircle the connector body 48. Again, no tools are required, such as a screwdriver, a sewing needle, a soldering iron, or a blow-torch. Thus, the engagement is toolless. The locking cover 30 is moved to the disengaged position. When the locking cover 30 prevents or inhibits access to the internal components of the device 10 such that the risk of injury to the user is reduced or eliminated. The spool 36 is free to rotate again, such that the winding mechanism 38 rotates the spool 36 in the winding direction. The leash 12 is retracted into the device 10 and wound around the barrel 36a. Optionally, the user may slow or prevent retraction of the leash 12 into the device 10 by engaging the unwinding-locking element 32. The kit with the leash 12 being received at least in part in the device 10 may be used similarly to a standard, retractable lead of the prior art. Thus, there is provided a method of connecting a leash 12 to the leash-storage device 10, the method comprising the steps of: a] obtaining a kit 14, wherein the leash 12 and the leashstorage device 10 are disconnected from each other; and b] connecting the leash 12 to the leash-connector 42. Referring now to Figures 13 to 15, there is provided a second embodiment of a kit 114 comprising a leash 112 and a device 110. The leash 112 and the device 110 of the second embodiment are similar to the leash 12 and device 10 of the first embodiment. Features of the second embodiment which are identical or similar to the first embodiment have similar reference numerals, with the prefix “1” added. The leash 112 of the second embodiment is similar or identical to the leash 12 of the first embodiment, having similar or identical flexible elongate element 116, device-engagement portion 118, the device-engagement portion 118 including a loop 118a, connector, removalfacilitating portion, first leash end 116a, second leash end 116b, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. The device 110 of the second embodiment is similar or identical to the device 10 of the first embodiment, having similar or identical casing 122, inner chamber 124, engagement portion, retraction mechanism 128, locking cover 130, and unwinding-locking element, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. Optionally, the locking cover 130 may be referred to as a flap. The locking cover 130 is moveable as per the first embodiment. However, the locking cover 130 of the second embodiment is preferably non-translatably movable, although this could be additionally envisioned. The device 110 further includes a hinge or hinge element 156. The locking cover 130 is preferably connected to the casing 122 by the hinge element 156. Thus, the locking body 150a is preferably pivotably or hingeably moveable between the engaged position and the disengaged position. The mechanism-engagement portion 150b extends outwardly from the locking body 150a when the locking body 150a is in the disengaged position, unlike the first embodiment. The locking cover 130 preferably has no blocking portion in the second embodiment but this can easily be envisioned, such as in the form of a hook, hook and loop engagement portions such as Velcro (RTM), or interference fit poppers by way of examples only. The blocking portion may even be a lug or groove, and the locking cover may be translatable after being pivoted such that the lug or groove enters into engagement with a complementary engagement portion, such that the locking cover is prevented or inhibited by the lug or groove from accidentally transitioning from the engaged position to the disengaged position. Thus, the locking cover may be both translatable and pivotable. In the second embodiment, the casing 122 has preferably no secondary chamber and / or no casing plate. There are preferably no engagement portions. The casing 122 further comprises a casing through-bore 158. At least part of the spool 136, and more preferably at least one of the flanges 136b may further include a spool through-bore 160. The casing through-bore 158 preferably overlaps or overlies the spool through-bore 160. In other words, the casing through-bore 158 and the spool through-bore 160 are aligned or alignable. The casing through-bore 158 and / or the spool through-bore 160 are preferably spaced apart from the hinge element 156 by a distance equal to or substantially equal to the distance between the mechanism-engagement portion 150b and the hinge element 156. The casing through-bore 158 and / or the spool through-bore 160 are also preferably sized and dimensioned so as to receive at least part of the mechanismengagement portion 150b therethrough when the locking cover 130 has been pivoted into the engaged position. Preferably, the locking cover 130 in the second embodiment, comprises a user-engagement portion or user-grip portion 162. In the second embodiment, the user-grip portion 162 includes a user-engageable lip, flange or finger grip. The uses of the second embodiment are similar to the uses of the first embodiment. Detailed description of the common steps and of the caveats is omitted for brevity. The user engages with the user-engagement portion 162 if provided. In the illustrated embodiment, this involves the user hooking their finger or fingers under the finger grip. To move the locking cover 130 from the disengaged position to the engaged position, the locking cover 130 is pivoted or rotated around the hinge element 156, as indicated by Arrow F in Figure 13. This results in the mechanism-engagement portion 150b being inserted through the casing through-bore 158. If the spool 136 has a spool through-bore 160, the mechanism-engagement portion 150b is also inserted into the spool through-bore 160. The mechanism-engagement portion 150b provides a physical abutment element against which the spool 136 abuts, the spool 136 thereby being prevented or inhibited from rotating. The action of fully uncoiling the leash 112 from around the spool 136 may result in the spool 136 being rotated until it reaches a position where the spool through-bore 160 and the casing through-bore 158 are aligned or overlapping. In the absence of a spool through-bore 160 or in the case of misalignment of the spool through-bore 160 and the casing through-bore 158, the mechanism-engagement portion 150b may alternatively prevent or inhibit rotation of the spool 136 by abutting against the spool to provide friction. Thus, the mechanism-engagement portion 150b may function as a brake. The second leash end 116b is disengaged from leash-connector 142. As the leashconnector 142 once again preferably includes a connector body 148 terminating at a free end portion 148a, the second leash end 116b, and more preferably the device-engagement portion 118 is moved, preferably by translation out of engagement with the leash-connector 142, as indicated by Arrow H. When the user wishes to store the leash 112 inside the device 110, the user re-engages the leash 112 with the leash-connector 142, preferably by translating the device-engagement portion 118 into engagement with the leash-connector 142. The locking cover 130 may be pivoted back into the disengaged condition. Referring now to Figure 16, there is shown part of a leash 212 of a third embodiment of a kit 214. The third embodiment of the kit 214 is similar to the first embodiment of the kit 14. Features of the third embodiment which are identical or similar to the first embodiment have similar reference numerals, with the prefix “2” added. The device of the third embodiment is similar or identical to the device of the first embodiment, having similar or identical casing, inner chamber, engagement portion, retraction mechanism, locking cover, and unwinding-locking element, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. The leash 212 of the third embodiment is similar or identical to the leash 12 of the first embodiment, having similar or identical flexible elongate element 216, device-engagement portion 218, connector, removal-facilitating portion, first leash end, second leash end 216b, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. Preferably, the leash 212 of the third embodiment includes a plurality of loops 218a. The loops 218a are preferably formed by folding the flexible elongate element 216 twice to form a large loop, a first fold 264a and a second fold 264b. The flexible elongate element 216 is connected to itself by a connection 266, preferably by an adhesive or a sewn connection 266. The connection 266 is intermediate between the first fold 264a and the second fold 264b and forms two smaller loops 218a out of the large loop. If a greater number of smaller loops is required, a plurality of connections may be provided between the first fold and the second fold to connect the flexible elongate element to itself in a plurality of spaced-apart locations. The terminal portion 216b’ of the second leash end 216b may optionally terminate at the or a said connection 266, as shown in Figure 16. The leash-connector may be similar or identical the leash-connector 42 of the first embodiment. Alternatively, the leashconnector may even have a plurality of connector bodies, each optionally terminating at a free end portion. The uses of the third embodiment are similar to those of the first embodiment. Detailed description of the common features and of the caveats is omitted for brevity. The user may have a choice of which loop 218a to engage with the leash-connector and / or with the connector body or bodies thereof. If the leash-connector has a plurality of connector bodies, the at least two loops 218a may be engageable or engaged with at least two connector bodies simultaneously. Referring now to Figure 17, there is shown part of a leash 312 and a leash-connector of a fourth embodiment of a kit 314. The fourth embodiment of the kit 314 is similar to the first embodiment of the kit 14. Features of the fourth embodiment which are identical or similar to the first embodiment have similar reference numerals, with the prefix “3” added. The device 310 of the fourth embodiment is similar or identical to the device 10 of the first embodiment, having similar or identical casing, inner chamber, engagement portion, retraction mechanism, locking cover, and unwinding-locking element, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. The leash-connector 342 has a plurality of connector bodies 348 each terminating at a free end portion 348a. Each connector body 348 is formed as a boss, and more preferably a cylindrical boss, but the exact shape of the boss is not essential. The leash 312 of the fourth embodiment is similar or identical to the leash 12 of the first embodiment, having similar or identical flexible elongate element 316, device-engagement portion 318, connector, removal-facilitating portion, first leash end, second leash end 316b, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. Preferably, the leash 312 of the fourth embodiment includes a plurality of loops 318a. The loops 318a are preferably formed by folding the flexible elongate element 316 once to form a large loop and a first fold 364a. The flexible elongate element 316 is connected to itself by a connection 366, preferably an adhesive or a sewn connection 366 in at least one, and more preferably a plurality of locations. The terminal portion 316b’ of the second leash end 316b is connected to the flexible elongate element 316 at a first said connection 366, as shown in Figure 17. At least one second said connections 366 is intermediate between the first fold 364a and the first said connection 366. The second said connection 366 forms two smaller loops 318a out of the large loop.

To connect the leash 812 to the device 810, the user inserts the leash 812 into the space 884 then into the gaps 874. No pivoting is required in the ninth embodiment. The leash portion of greater thickness T may abut against a side of one or preferably the plate elements 878. The abutment of leash portion of greater thickness T against the plate element or plate elements 878 may prevent or inhibit the leash 812 from being accidentally pulled longitudinally through the gaps 874 and out of engagement with the leash-connector 842 entirely. Referring now to Figure 24, there is shown part of a leash 912 and a leash-connector 942 of a tenth embodiment of a kit 914. The tenth embodiment of the kit 914 is similar to the first embodiment of the kit 14. Features of the tenth embodiment which are identical or similar to the first embodiment have similar reference numerals, with the prefix “9” added. The device of the tenth embodiment is similar or identical to the device 10 of the first embodiment, having similar or identical casing, inner chamber, engagement portion, retraction mechanism, locking cover, and unwinding-locking element, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. The leash-connector 942 has a supporting portion 972 and a leash-redirecting plate 986. The supporting portion 972 and leash-redirecting plate 986 together form a gap 974. The leash-connector 942 of the tenth embodiment may be referred to as a ladder lock buckle. The leash-connector 942 may include metal and / or plastics. The leash 912 of the tenth embodiment is similar or identical to the leash 12 of the first embodiment, having similar or identical flexible elongate element 916, device-engagement portion 918, connector, removal-facilitating portion, first leash end, second leash end 916b, but any of the above may be omitted and / or a plurality of any of the above may be provided.

The terminal portion 916b’ of the second leash end 916b may optionally be folded to provide a leash portion of greater thickness T. The uses of the tenth embodiment are similar to those of the first embodiment. Detailed description of the common features and of the caveats is omitted for brevity. To connect the leash 912 and the device, the user pushes the leash 912 through the gap 974. The leash-redirecting plate 986 causes the leash 912 to be deformed so as to increase the friction between the leash 912 and the leash-connector 942. Abutment of the leash portion of greater thickness T against the leash-redirecting plate 986 may further prevent or inhibit the leash 912 being accidentally pulled out of the leash-connector 942. To disconnect the leash 912, the leash 912 is pulled through the gap 974 by the user. Referring now to Figure 25, there is shown part of a leash-connector 1042 of an eleventh embodiment of a kit 1014. The eleventh embodiment of the kit 1014 is similar to the tenth embodiment of the kit 914. Features of the eleventh embodiment which are identical or similar to the tenth embodiment have similar reference numerals, with the prefix “10” replacing the previous prefix. The device 1010 of the eleventh embodiment is similar or identical to the device 910 of the tenth embodiment, having similar or identical casing, inner chamber, engagement portion, retraction mechanism, locking cover, and unwinding-locking element, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. The leash-connector 1042 has supporting portion 1072 and at least one leash-redirecting plate 1086. The leash of the eleventh embodiment is similar or identical to the leash 912 of the tenth embodiment, having similar or identical flexible elongate element, device-engagement portion, connector, removal-facilitating portion, first leash end, second leash end, but any of the above may be omitted and / or a plurality of any of the above may be provided. Detailed description of the common features and of the caveats is omitted for brevity. The uses of the eleventh embodiment are similar to those of the tenth embodiment. Detailed description of the common features and of the caveats is omitted for brevity. The leash-redirecting plate 1086 causes redirection of the leash and thereby increases the friction between the leash and the leash-redirecting plate 1086. In the above embodiments, the locking cover and the unwinding-locking element are two distinct locking elements or locking mechanisms. However, it could be envisioned for simplicity of use and / or of manufacturing, that the locking cover and the unwinding-locking element could be the same locking element. For example, a single locking element could be envisioned to prevent or inhibit rotation of the spool in the winding direction and / or in the unwinding direction. For example, the user-interactable element may be provided with a brake or brake pad instead of or in addition to the one or more pawl elements. In any of the embodiments, the leash-connector and / or the leash may comprise a connection element which may be at least in part formed of a hard material. The hard material may be metal, plastics, carbon fibre, glass fibre, wood, fabric, any other suitable material, any combination thereof. Any alternative or additional device-engagement portion and / or leash-connector may be envisioned. For example, the device-engagement portion and / or leash-connector may comprise complementary bayonet portions, or complementary screw-threads, by way of examples only. Furthermore, the casing plate may be omitted in any of the above embodiments. Instead or in addition to the casing plate, the casing may comprise guiding grooves or tracks for guiding the locking cover between the engaged position and the disengaged position. In any of the above embodiments where the second leash end includes a loop receivable around the connector body, the loop may have a sufficient thickness so as to be held in place, such as between the connector body and the spool due to the thickness. In other words, the second leash end may not necessarily be received or receivable around the connector body. Optionally, the second leash end may be fully connected to itself such that no loop is formed. Instead of a coil spring, the winding mechanism may alternatively comprise a wheel, gear or gear set. The wheel or gear may abut against the spool, such as the barrel and / or a flange thereof. The wheel or gear may be powered to be selectively rotatable. The winding mechanism may comprise a power source. Rotation of the wheel or gear may cause rotation of the spool. When the wheel or gear are non-rotating, the wheel or gear may prevent or inhibit rotation of the spool. Optionally, such as winding mechanism may additionally function as a locking element. Friction between the spool and the wheel or gear may be sufficient to cause, prevent or inhibit rotation of the spool. Optionally, the wheel or gear may comprise teeth and the spool may further comprise a complementary set of teeth. Any of the features and caveats that apply to any one of the embodiments may easily be provided or applicable to any of the other embodiments in any combination. Whilst a preferred shape may have been specified for any of the above-described features, any alternative shape may be envisioned in any of transverse or lateral cross-section, longitudinal cross-section, in side view, or in plan view. The shape may be any or any combination of: curved, part curved, non-curved, linear, part linear, non-linear, a broken line, any polygon, whether regular or irregular, having one or more chamfered and / or rounded corners, a triangle, a quadrilateral, such as a square, a rectangle, a trapezium, a trapezoid, a pentagon, a hexagon, a heptagon, an octagon, or any other polygon, a cross, an ellipse, a circle, part circular, an oval, or any abstract shape. It is therefore possible to provide a leash-storage device which enables a long lead, such as a training lead, to be spooled and stored within the device. The leash can be used whilst being attached to the device, the device providing a handle for the user. By being connectable and disconnectable from the leash-storage device, the leash may also be fully removed out of the device when required, such that the same leash may be used as a retractable leash and a training leash, negating the need for the user to carry two different leashes. Storage within the device increases the compactness and / or prevents or inhibits the leash from becoming tangled. The device may also protect the leash from damage and / or becoming dirty. It is therefore also possible to provide a versatile leash which can be used either as a training leash or as a retractable leash, by virtue of being selectably connectable to and spoolable within a leash-storage device. To this effect, the leash includes a device-engagement portion that can be engaged with a leash-storage device. It is further possible to provide a kit including both the leash and the device. The versatile leash can be retracted and stored compactly within the device when desired. It is also possible to provide a method of connecting the leash to the device and a method of disconnecting the leash from the device. The ability to connect and disconnect the leash from the device enables a single leash to function as a retractable lead and as a training lead when required. Only one lead is required where two leads were previously required. This reduces costs and is environmentally friendlier by virtue of using fewer resources. The leash can be replaced when damaged and / or for customisability. The words ‘comprises / comprising’ and the words ‘having / including’ when used herein with reference to the present invention are used to specify the presence of stated features, integers, steps or components, but do not preclude the presence or addition of one or more other features, integers, steps, components or groups thereof. It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination. The embodiments described above are provided by way of examples only, and various other modifications will be apparent to persons skilled in the field without departing from the scope of the invention as defined herein.
