[0002] “Closure system and a product with a closure system”

[0003] The invention relates to a closure system. In particular, this closure system is suitable for closing the opening of a bag or suitcase. This closure system comprises a plug-in part and a receiving part. The plug-in part has a holding element which can be inserted into the receiving part through a receiving opening in the receiving part in a plug-in direction and is designed to be reversibly locked from an open state to a closed state by means of a locking mechanism arranged in the receiving part. Furthermore, the invention relates to a product in which at least two elements to be connected are connected to one another by means of such a closure system.

[0004] Such closure systems are known, for example, as snap or latch closures and can be conveniently used in a variety of bags, pouches, or cases, in particular handbags or cosmetic cases. For example, in a handbag that closes a filling opening of a receiving body with a flap, the plug-in part or the receiving part is arranged on a first element to be connected. This first element is, in particular, a lid or a flap of the handbag. The other plug-in part or the receiving part is arranged on a second element to be connected. This second element is, in particular, a wall of the receiving body of the handbag.In a known manner, the flap is connected on one side to the wall of the receiving body, so that the flap can be placed over the filling opening and can be reversibly fixed to the receiving body opposite the connection between the flap and the receiving body by means of the locking system.

[0005] However, such closure systems are not exclusively advantageous for bags or suitcases. In particular, containers of any kind or items of clothing in which two elements must be connected to each other, e.g., a belt, can also have such a closure system to provide the connecting function. In particular, within the meaning of the application, it may be provided that the elements to be connected are actually physically formed as one piece. Therefore, in the case of a belt, the ends of the belt are each considered individually as a single element to be connected.

[0006] Even if such snap fasteners meet the requirements in terms of their connection and / or holding properties, it has proven disadvantageous in the prior art that protruding elements, especially the holding element, can easily become caught on other objects, such as clothing. This frequently leads to damage to the clothing.

[0007] Furthermore, retaining elements of the known type are often made of a very hard material, especially metal, and / or equipped with sharp locking elements, so that a common problem is that other objects in the vicinity are scratched or damaged. Especially in environments such as laboratories and / or healthcare facilities, where, for example, thin gloves, especially those made of latex, are worn, conventional closure systems with protruding hard and / or sharp elements have significant disadvantages. In this sense, hard and / or sharp elements of the closure system also pose a risk of injury to the user.

[0008] In particular, when reaching through the unlocked opening of a bag, protruding elements of the closure system can cause injuries to the hands or damage to gloves, sleeves of clothing and the like.

[0009] Furthermore, protruding elements are exposed to environmental influences, meaning that if damage occurs, for example, to the retaining element, the closure system no longer closes reliably. Another disadvantage is the visual and / or tactile appearance of the closure systems; users often find protruding elements unsightly.

[0010] While magnetic closure systems are known that generally do not have any protruding elements, these have the disadvantage that they can damage electronic devices or bank cards placed in a handbag or impair their functionality. Furthermore, magnetic closure systems often have either too little closure force or too much closure force, but require an uncomfortably high release force to separate the elements.

[0011] The invention is based on the object of providing a closure system and a product with such a closure system which overcomes the disadvantages known from the prior art, in particular increases safety during use and is preferably aesthetically pleasing.

[0012] The object is achieved according to the invention by the features of claim 1 in that the holding element is movably mounted in the plug-in part such that in the permanently closed state it protrudes from the plug-in part pointing in the plug-in direction with a longer projection to a plug-in side of the plug-in part pointing in the plug-in direction than in an open state of the plug-in part separated from the receiving part.

[0013] The design according to the invention has the advantage that the holding element protrudes less from the plug-in part when the closure system is in the open state than when it is in the closed state. In the open state, the holding element is at least partially arranged or retracted into the plug-in part, wherein in particular a possibly pointed or sharp-edged holding geometry is arranged in the plug-in part for interaction with the locking mechanism. This is possible because in the contactless open state, the holding element does not perform any function and therefore does not require any projection to the plug-in side of the plug-in part. Due to the reduced projection, the holding element poses a lower risk of injury or damage, and the visual and tactile appearance is less or not adversely affected by the holding element.

[0014] In particular, it can be provided that, in the open state of the plug-in part separated from the receiving part, the holding geometry of the holding element, preferably the holding element, is arranged completely within the plug-in part or, preferably, the holding element is flush with the plug-in side of the plug-in part. According to this embodiment, the holding element poses virtually none of the risks mentioned above. Furthermore, in the open state of the plug-in part separated from the receiving part, the holding element can be designed to be flush with the plug-in part in such a way that the penetration of dirt and / or moisture into the plug-in part is prevented or reduced.A further advantage, particularly in this embodiment, is that the holding element can be made of a hard material and / or can have a sharp-edged and / or pointed holding geometry, which, in the separated, open state of the plug-in part, is received by the receiving part in the plug-in part and is shielded from the environment.

[0015] The plug-in part and / or the receiving part can expediently be made of a soft material and / or with rounded transitions. According to a particular embodiment, the elements within the plug-in part and / or the receiving part, in particular the retaining element and / or the locking mechanism and / or optional contact elements, are preferably made of a harder material, in particular a metal or a metal alloy, than the receiving part and / or the plug-in part, which are, for example, made of a plastic or a natural material such as wood.

[0016] In a preferred embodiment of the invention, at least one contact element is movably mounted in the plug-in part such that it is displaceable relative to the plug-in part, counter to the plug-in direction. In particular, the contact element is designed to be displaceable in and counter to the plug-in direction. Preferably, the contact element is designed such that a displacement of the contact element is transmitted to the retaining element for protruding or moving out of the plug-in part. In particular, the contact element is designed as a pin. The contact element is expediently designed as a cuboid-shaped or cylindrical pin.

[0017] Advantageously, the contact element can be made entirely or partially from a metal or a metal alloy.

[0018] To transmit or convert the movement of the contact element to the movement of the holding element, a special embodiment provides for the plug-in part to have a transmission device that transmits the movement of the contact element to the movement of the holding element. Particularly preferably, it is provided that when the contact element is displaced relative to the plug-in part in the opposite direction to the insertion direction, the holding element is displaced relative to the plug-in part in the insertion direction or is pushed out of the plug-in part.An exemplary transmission device can, for example, comprise a rocker element, wherein a first free end of the rocker element is operatively connected to the contact element, and a second free end of the rocker element is operatively connected to the holding element, and the rocker element is mounted on a rotational axis between the first and second free ends in such a way that, for example, a displacement of the first free end counter to the plug-in direction causes a displacement of the second free end in the plug-in direction. In particular, a transmission ratio can be set by positioning the rotational axis relative to the first and second free ends of the rocker element.

[0019] Preferably, the transmission device has a transmission ratio such that, upon displacement of the contact element relative to the plug-in part, pointing counter to the plug-in direction, the holding element is pushed out of the plug-in part relative to the plug-in part, pointing in the plug-in direction, by a distance which is greater than the displacement of the contact element relative to the plug-in part, pointing counter to the plug-in direction. Such a transmission ratio can expediently be set for the rocker element by positioning the rotational axis closer to the first free end connected to the contact element than to the second free end connected to the holding element. The transmission ratio of the movement of the contact element to the movement of the holding element is preferably in a range from a ratio of 1 to 2 to a ratio of 1 to 5.

[0020] It is expediently provided that the contact element advantageously projects into / through an opening on the plug-in side of the plug-in part. Preferably, when the plug-in part is in the open state separated from the receiving part, the contact element projects out of the plug-in part through this opening with a free end pointing in the plug-in direction and with an overhang towards the plug-in side of the plug-in part. It is preferable that the contact element is displaceable relative to the plug-in part by means of a force acting on the free end counter to the plug-in direction. Preferably, the contact element has rounded surface transitions. In particular, the free end is rounded. The rounding prevents sharp-edged transitions on the contact element, thus preventing injuries and damage in particular.

[0021] Particularly advantageously, the aforementioned force is applied to the free end of the contact element by means of a receiving side of the receiving part, wherein the receiving opening is formed on the receiving side, which is brought into contact with the contact element of the plug-in part. By bringing the plug-in part and the receiving part together, wherein the plug-in side and a receiving side of the receiving part are aligned facing each other, the receiving part exerts a force on the contact element by bearing against the free end of the contact element, so that the contact element is displaced relative to the plug-in part against the plug-in direction. The relative position of the contact element to the receiving part or the receiving side remains unchanged during this process.Advantageously, the contact element can be designed such that, when the contact element rests against the receiving side of the receiving part, the length of the projection of the retaining element relative to the plug-in side of the plug-in part increases when the distance between the plug-in side of the plug-in part and the receiving side of the receiving part decreases, and decreases when the distance between the plug-in side of the plug-in part and the receiving side of the receiving part increases. According to this embodiment, a variable projection of the retaining element relative to the plug-in side of the plug-in part is advantageously automatically adjusted by the approach or distance of the plug-in part to the receiving part.

[0022] Preferably, to protect the receiving part or the receiving side, at least the free end of the contact element can be formed from a plastic or rubber and / or covered with a protective layer, in particular from a plastic or rubber.

[0023] For functional purposes, it is also advantageous if the contact element is mounted so as to be movable relative to the plug-in part, pointing counter to the plug-in direction, against a preload force. In particular, the preload force can be provided by means of a tensioning element, in particular a spring or other elastic element. The tensioning element is expediently connected directly to the contact element. Also advantageous is an embodiment in which the contact element, which is movable against the preload force, is connected to the transmission device and the holding element in such a way that the tensioning element acting on the contact element simultaneously preloads the holding element, for example via the rocker element, against movement in the plug-in direction relative to the plug-in part. This has the advantage that, with just one tensioning device, synergistically independent retraction into the plug-in part is provided for the holding element.Additionally or alternatively, it can be provided that the clamping means acts directly on the holding element and / or on the transmission device and thereby indirectly on the contact element. In order to advantageously provide a particularly uniform plugging process, it can be provided that the plug-in part has two or more contact elements of the aforementioned type. In particular, two or more contact elements are each connected to the holding element via a transmission device and / or a common transmission device. The respective transmission device is expediently designed according to one of the aforementioned embodiments.

[0024] The retaining element preferably has a retaining geometry which, in the locked, closed state, is reversibly engaged behind by a locking geometry of a locking hook of the locking mechanism of the receiving part arranged in the receiving part. The retaining geometry can have a locking step for engagement by the locking hook, which can be formed, for example, by an opening in the retaining element, a groove, a notch, or a ramp rising counter to the insertion direction. By means of the retaining geometry, the retaining element can advantageously be blocked in the receiving part in the locked, closed state, at least in a form-fitting manner, facing counter to the insertion direction.

[0025] According to an advantageous embodiment, the locking hook is pivotably mounted within the receiving part between a blocking position, in which the locking geometry can engage behind the holding geometry and block the holding element, and a release position, in which the blocking of the holding element is released. Preferably, the pivoting arrangement of the locking hook advantageously allows the blocking of the holding element against movement opposite to the insertion direction to be released.

[0026] Particularly in combination with the pivoting arrangement of the locking hook, a special design provides for the locking mechanism to have a clamping means such that the locking hook is subjected to a clamping force to prevent it from being transferred from the blocking position to the release position, such that the locking hook is always forced into its blocking position. This facilitates, in particular, the locking of the retaining element with the locking mechanism and the connection of the plug-in part with the receiving part.

[0027] Furthermore, the locking of the holding element with the locking mechanism or the connection of the plug-in part with the receiving part is facilitated by a special variant in that the locking mechanism, in particular the locking hook and the holding element, are designed to correspond to one another in such a way that when the holding element is inserted into the receiving part, the holding element can pivot the locking hook, in particular against the clamping force, out of the blocking position. It is expediently provided that the locking hook, when the holding element is inserted so far in the plug-in direction that the holding geometry of the holding element is arranged in front of the locking geometry of the locking hook, viewed in the plug-in direction, can be transferred into its blocking position, in particular is transferred with the clamping force and engages behind the holding geometry with the locking geometry.In this case, it can be expediently provided that, in a maximum state of the holding element inserted into the receiving part, the holding geometry of the holding element is arranged in front of the locking geometry of the locking hook, viewed in the plug-in direction.

[0028] In particular, separating the receiving part from the plug-in part is facilitated by the fact that, in a special embodiment, the receiving part has a release device that can be actuated from outside the receiving part. The release device is expediently connected to the locking mechanism, in particular the locking hook, in such a way that upon actuation of the release device, the locking hook is moved from the blocking position to the release position. Preferably, the release device can be actuated from outside the receiving part using a pushbutton switch or a lever.

[0029] The release device is preferably designed as a pushbutton switch that is flush with the receiving part and is configured such that the pushbutton switch can be partially pressed into the receiving part for actuation. In particular, a pushbutton switch that can be pressed into the receiving part has proven advantageous because it can be arranged and actuated without projecting from the receiving part. The pushbutton switch expediently has a rest position in which the pushbutton switch is flush with the receiving part and an action position in which it is pressed into the receiving part. It can be provided that the pushbutton switch is subjected to a clamping force that can transfer the pushbutton switch to its rest position.In this sense, it is provided in a particularly advantageous variant that the push button interacts with the locking mechanism in such a way that the push button is synergistically pushed into its rest position by means of the advantageous clamping means of the locking mechanism.

[0030] The object underlying the invention is further achieved by means of a product according to the invention. The product can be, in particular, a transport aid, such as a bag, a container, such as a can or chest, or a piece of clothing, such as a belt. According to the invention, the product has at least one closure system according to the invention of the aforementioned type. By means of this at least one closure system, at least two elements can be reversibly connected. For this purpose, it is provided that the male part of the closure system is arranged on one of the elements to be connected and the female part is arranged on another of the elements to be connected.

[0042] With regard to the following description, it is claimed that the invention is not limited to the exemplary embodiments and not to all or several features of described combinations of features, but rather each individual partial feature of the / each exemplary embodiment is also important for the subject matter of the invention, even independently of all other partial features described in connection therewith, and also in combination with any features of another exemplary embodiment.

[0043] 1 and 2 show a closure system 1 which is particularly suitable for closing the opening of a bag or a suitcase. The closure system 1 has a plug-in part 2 which is shown in FIGS. 3 to 6 and a receiving part 4 which is shown in FIGS. 7 and 8. The plug-in part 2 expediently has a plug-in part housing 8 and the receiving part 4 has a receiving part housing 6. In particular, the plug-in part housing 8 and / or the receiving part housing 6 is / are designed in at least two parts, wherein expediently a lower housing part 10 is provided which forms a receiving space with housing walls 14 which run at least partially around it, and in particular an upper housing part is provided which is expediently designed as a cover and closes the receiving space. The upper housing part is not shown.In particular, the upper housing part can be designed to be detachable and reconnectable to the lower housing part 10, in particular by means of a snap-in and / or screw connection. This advantageously allows access to the receiving space, in particular for maintenance and repair purposes.

[0044] It is provided that the plug-in part 2 has a holding element 16. The holding element 16 can be inserted into the receiving part 4 in a plug-in direction S through a receiving opening 18 of the receiving part 4, shown in Fig. 7. The receiving opening 18 is advantageously formed on a receiving side 19 of the receiving part 4. The plug-in direction S is identified in particular in Figs. 1, 4 and 8. In the receiving part 4, as shown in Figs. 7 and 8, a locking mechanism 20 is arranged, by means of which the holding element 16 can be reversibly locked in the receiving part 4.

[0045] According to the invention, the holding element 16 is movably mounted in the plug-in part 2, in particular in the receiving space of the lower housing part 10 of the plug-in part 2. The invention provides that, at least in a rusted, closed state of the holding element 16 in the receiving part 4, the holding element 16 protrudes from the plug-in part 2 pointing in the plug-in direction S, as shown in Figs. 2 and 6, with a longer projection toward a plug-in side 22 of the plug-in part 2 pointing in the plug-in direction S than in an open state of the plug-in part 2 separated from the receiving part 4, as shown in Figs. 1 and 5.

[0046] 4 and 5, a particularly advantageous embodiment provides that, in the open state of the plug-in part 2, separated from the receiving part 4, the holding element 16 is arranged completely in the plug-in part 2, in particular in the plug-in part housing 8. In the variants shown in Figs. 4 and 5, the holding element 16, in the open state of the plug-in part 2, separated from the receiving part 4, advantageously ends flush with the plug-in side 22 of the plug-in part 2. In particular, it is provided that an opening on the plug-in side 22 of the plug-in part 2, through which the holding element 16 can protrude from the plug-in part 2, is designed to correspond to the holding element 16 in such a way that, in the open state of the plug-in part 2, separated from the receiving part 4, the holding element 16 closes the opening with a free end pointing in the plug-in direction S.

[0047] According to a preferred embodiment, at least one contact element 26 is movably mounted in the plug-in part 2 such that it is displaceably mounted relative to the plug-in part 2 counter to the plug-in direction S. In particular, the contact element 26 is designed such that a displacement of the contact element 26 is transmitted to the holding element 16 for protruding or moving out of the plug-in part 2. The contact element 26 is expediently mounted movably within a contact path 24 relative to the plug-in part 2. The contact path 24 is identified in Fig. 4. A preferred embodiment provides that the plug-in part 2, corresponding to the embodiment of the plug-in part 2 shown in Figs. 3 to 6, has two contact elements 26, wherein the holding element 16 is arranged between the two contact elements 26.In particular, the direction of movement of the contact element 26 relative to the plug-in part 2 and the direction of movement of the holding element 16 relative to the plug-in part 2 are parallel to each other.

[0048] In particular, the contact element 26 is designed as a pin. The contact element 26 is expediently designed as a cuboid-shaped or cylindrical pin.

[0049] According to an advantageous embodiment, the plug-in part 2 has a transmission device. The transmission device is shown in particular in Fig. 4. In particular, the transmission device is designed such that it transmits the movement of the contact element 26 to the movement of the holding element 16 such that when the contact element 26 is displaced relative to the plug-in part 2 against the plug-in direction S, the holding element 16 is displaced relative to the plug-in part 2 in the plug-in direction S or is pushed out of the plug-in part 2. Such an effect can expediently be generated by a rocker element 28, as shown in Fig. 2. The displacement of the holding element 16 based on a displacement of the contact elements 26 becomes apparent in particular from a comparison of the different states in Figs. 5 and 6.

[0050] Preferably, the transmission device has a transmission ratio such that when the contact element 26 is displaced relative to the plug-in part 2 against the plug-in direction S, the holding element 16 is displaced relative to the plug-in part 2 in the plug-in direction S out of the plug-in part 2 by a distance which is greater than a displacement of the contact element 26 relative to the plug-in part 2 against the plug-in direction S.

[0051] In an advantageous rocker element 28, it is expediently provided that a first free end of the rocker element 28 is operatively connected to the contact element 26, and a second free end of the rocker element 28 is operatively connected to the holding element 16, and between the first and second free ends, the rocker element 28 is mounted on a rotation axis 30 in such a way that, for example, a displacement of the first free end pointing against the plug-in direction S causes a displacement of the second free end pointing in the plug-in direction S. In particular, the plug-in part 2, as shown in particular in Figs. 1 to 6, has two rocker elements 28, each rocker element 28 being connected at one free end to a respective contact element 26 and at the other free end to the holding element 16, the holding element 16 and the contact elements 26 being each rotatably attached to the rocker element 28 according to a preferred arrangement.The contact element preferably has rounded surface transitions. In particular, the free end is rounded. A favorable transmission ratio can be expediently set for the rocker element 28 by positioning the rotational axis 30 closer to the first free end connected to the contact element 26, as shown in Fig. 4, than to the second free end connected to the holding element 16. In particular, when the contact element 26 is displaced relative to the plug-in part 2 against the plug-in direction S, the holding element 16 is pushed further out of the plug-in part 2 than the contact element is pushed into the plug-in part 2.

[0052] It can also be provided that the plug-in part 2 has an elastic stop means 32 on at least one section of the housing wall 14 adjacent to the transmission device and / or the contact element 26, so that upon deflection of the contact element 26 and / or the transmission device, the respective components do not come into contact with the respective section of the housing wall 14. In Figs. 1 to 6, only one elastic stop means 32 is provided, which is designed in particular to cushion the plug-in mechanism, or the lever transmission, in front of the housing wall 14 of the plug-in part 2.

[0053] 4 to 6, the contact element 26 can be designed and arranged in such a way that, in order to displace the contact element 26 pointing in the plug-in direction S and / or pointing against the plug-in direction S, the contact element 26 can be acted upon from outside the plug-in part 2. In particular in the advantageous exemplary embodiment shown in Figs. 4 and 5, the contact element 26 projects into / through an opening on the plug-in side 22 of the plug-in part 2. In the open state of the plug-in part 2, separated from the receiving part 4, the contact element 26 expediently projects out of the plug-in part 2 with the free end 34 pointing in the plug-in direction S with a projection 36 towards the plug-in side 22 of the plug-in part 2.In particular, it is provided that the projection 36 corresponds at least to the contact path 24 and the contact element 26 can be displaced relative to the plug-in part 2 by means of a force acting on the free end 34 directed against the plug-in direction S.

[0054] In particular, it is provided that the force acting on the free end 34 of the contact element 26 for displacing the contact element 26 relative to the plug-in part 2 occurs by means of the receiving part 4, in particular the receiving side 19 of the receiving part 4. Advantageously, the receiving part 4 or the receiving side 19 comes into contact with the contact element 26 of the plug-in part 2 during a connection process of the plug-in part 2 with the receiving part 4. Very particularly preferably, the receiving part 4 has at least one contact surface 12 on the receiving side 19, preferably one for each contact element 26, structured corresponding to the respective contact element 26. The receiving part 4 or the receiving side 19 is expediently designed such that during a connection process of the plug-in part 2 with the receiving part 4, the contact elements 26 of the plug-in part 2 come into contact with the contact surfaces 12 of the receiving part 4.The structured contact surfaces 12 are advantageously shown in Figs. 1 and 7.

[0055] From this first contact, the plug-in part 2 of the plug-in part 2 can be moved toward the receiving part 4 in the plug-in direction S. The receiving part 4 or the receiving side 19 advantageously exerts a force on the contact element 26 by contacting the contact element 26, so that the contact element 26 is displaced relative to the plug-in part 2 against the plug-in direction S. The relative position of the contact element 26 to the receiving part 4 or the receiving part 4 remains the same during this process. This embodiment advantageously enables the length of the projection of the holding element 16 relative to the plug-in side 22 of the plug-in part 2 to increase when the distance between the plug-in side 22 of the plug-in part 2 and the plug-in side 19 of the plug-in part 4 is reduced, and the length of the projection of the holding element 16 relative to the plug-in side 22 of the plug-in part 2 is reduced when the distance between the plug-in side 22 of the plug-in part 2 and the plug-in side 19 of the plug-in part 4 is increased ....According to this embodiment, a variable projection of the holding element 16 to the plug-in side 22 of the plug-in part 2 is advantageously automatically adjusted by the approach or distance of the plug-in part 2 to the receiving part 4.

[0056] Preferably, to protect the receiving part 4 or the receiving side 19, at least the free end 34 of the contact element 26 can be formed from a plastic or rubber and / or covered with a protective layer, in particular from a plastic or rubber.

[0057] Advantageously, the opening on the plug-in side 22 of the plug-in part 2, in which the contact element 26 is arranged or from which the contact element 26 can protrude from the plug-in part 2, is designed to correspond to the contact element 26 in such a way that the contact element 26 closes the opening all the way around. A seal can also be provided that seals the opening against the contact element 26, thus making it difficult or impossible for dirt and / or liquid to penetrate the plug-in part 2.

[0058] In particular, the contact element 26 is movably mounted relative to the plug-in part 2, pointing counter to the plug-in direction S, against a preload force. The preload force can expediently be provided by a tensioning element 38, in particular a spring or other elastic element. In the advantageous embodiment illustrated in Figs. 1 to 6, the tensioning element 38 is designed as a helical spring. It can expediently be provided that the tensioning element 38 is directly connected to the contact element 26.

[0059] A further advantageous embodiment is one in which the contact element 26, which is movable against the pretensioning force, is connected to the plug-in mechanism and the holding element 16 in such a way that the tensioning element 38 acting on the contact element 26 simultaneously pretensions the holding element 16 against movement in the plug-in direction S relative to the plug-in part 2, for example via the transmission device. This has the advantage that, with just one tensioning element 38, an independent retraction into the plug-in part 2 is provided synergistically for the holding element 16. Additionally or alternatively, it can be provided that the tensioning element 38 acts directly on the holding element 16 and / or on the transmission device and thus indirectly on the contact element 26. According to an advantageous embodiment, both the / each contact element 26 and the holding element 16 itself have their own tensioning element 38 designed as a helical spring.In particular, in this embodiment, the preload is distributed evenly over the contact elements 26 and the plug-in mechanism, so that an advantageous displacement of the holding element 16 and the contact elements 26 is provided against a preload force.

[0060] According to a preferred variant of the closure system 1, the holding element 16 has a holding geometry 40. In particular, the holding geometry 40, as shown in Fig. 6, is designed as an opening through the holding element 16. The holding element 16 is expediently configured such that, in the rusted, closed state, it is reversibly engaged behind by a locking geometry 42 of a locking hook 44, arranged in the receiving part 4, of the locking mechanism 20 of the receiving part 4. A preferred variant of the locking hook 44 with a locking geometry 42 is shown in Fig. 9. By engaging behind the locking hook 44 by means of the locking geometry 42, the holding element 16 can be blocked at least positively pointing against the plug-in direction S or is blocked in the rusted, closed state.

[0061] Preferably, as shown in Figs. 7 and 8, the locking hook 44 is pivotally mounted within the receiving part 4 between a blocking position, in which the locking geometry 42 can engage behind the holding geometry 40 and block the holding element 16, and a release position, in which a blocking of the holding element 16 can be released. According to the embodiment shown in Fig. 8, it can advantageously be provided that the locking mechanism 20 additionally has a tensioning means 46 such that the locking hook 44 is subjected to a tensioning force against a transfer from the blocking position to the release position such that the locking hook 44 is always urged into its blocking position.

[0062] It has also proven advantageous if the locking mechanism 20, in particular the locking hook 44 and the holding element 16, are designed to correspond to one another in such a way that when the holding element 16 is inserted into the receiving part 4, the holding element 16 can pivot the locking hook 44, in particular against the clamping force, out of the blocking position. In particular, the locking hook 44 can be transferred into its blocking position when the holding element 16 is inserted into the receiving part 4 so far in the plug-in direction S that the holding geometry 40 of the holding element 16 is arranged in front of the locking geometry 42 of the locking hook 44, viewed in the plug-in direction S. At this point in time, the holding element 16 is preferably in a state in which it is maximally inserted into the receiving part 4.The maximum insertion state of the holding element 16 into the receiving part 4 is expediently achieved when the plug-in part 2 rests with its plug-in side 22 against the receiving side 19 of the receiving part 4. By transferring the holding element 16 into its blocking position, which occurs in particular automatically by means of the clamping means 46 of the locking mechanism 20, the locking hook 44 with the locking geometry 42 engages behind the holding geometry 40 of the holding element 16, so that the holding element 16 or the plug-in part 2 is positively blocked against movement counter to the insertion direction S.

[0063] Figs. 7 to 9 illustrate a further advantageous embodiment, according to which the receiving part 4 has a release device that can be actuated from outside the receiving part 4. The release device is expediently connected, as shown in particular in Fig. 9, to the locking mechanism 20, in particular the locking hook 44, in such a way that upon actuation of the release device, the locking hook 44 is transferred from the blocking position to the release position.

[0064] In particular, the pushbutton switch 48 shown in Figs. 7 to 9 has proven to be advantageous. The pushbutton switch 48 expediently has a rest position in which the pushbutton switch 48 is flush with the receiving part 4, and an action position in which it is at least partially pressed into the receiving part 4. In particular, the locking mechanism 20 of the receiving part 4 is in a blocking position when the pushbutton switch 48 is in its rest position, wherein the pushbutton switch 48 is arranged in an operative connection with the locking mechanism 20 such that by transferring the pushbutton switch 48 from the rest position to its action position, the pushbutton switch 48 acts on the locking mechanism 20 and transfers the locking mechanism 20 into the release position, in particular against the clamping force, at least for the duration in which the pushbutton switch 48 is in its action position.

[0065] Preferably, the pushbutton switch 48 is subjected to a clamping force which urges the pushbutton switch 48 into its rest position in such a way that in order to transfer the button 48 from the rest position to the action position, the pushbutton switch 48 must be pressed or moved against the clamping force. In this sense, in a particularly advantageous variant, as in the exemplary embodiment shown in Figs. 7 and 8, the pushbutton switch 48 interacts with the locking mechanism 20 in such a way that the pushbutton switch 48 is synergistically urged into its rest position by means of the advantageous clamping means 46 of the locking mechanism 20. According to an alternative or supplementary embodiment, the pushbutton switch 48 itself has an additional switch spring 50, which is designed in particular as a helical spring. The switch spring 50 is preferably, as shown in Fig.9, at least partially arranged within the push button switch 48 such that the switch spring 50 is or is tensioned at least in the action position of the push button switch 48, between the push button switch 48 and the housing lower part 10 of the receiving housing 6 of the receiving part 2.
