Description

[0001] Hose clamp, hose clamp for securing a hose connection, hose connection and method for securing a hose connection

[0002] The present invention relates to a hose clamp bracket, a hose clamp for securing a hose connection, a hose connection and a method for securing a hose connection.

[0003] Traditionally, cable ties or one-piece securing elements such as ear clamps are used to secure hose connections after a hose has been pushed onto a connector. These options are complex. A cable tie must be manually placed around the connection point as a securing device and cannot guarantee a defined closing force because cable ties are displacement-controlled. One-piece securing elements must be pushed onto the hose before assembly from hose to connector and then pulled over the connection point. Special tools are often required to crimp the one-piece securing elements, and positioning and activating the securing elements can be problematic, especially in tight spaces.

[0004] It is therefore an object of the present invention to ensure a more efficient and effective securing of a hose connection.

[0005] This problem is solved by the independent patent claims. Advantageous embodiments emerge from the dependent patent claims.

[0006] A particularly first aspect of the invention relates to a hose clamp bracket for a hose clamp for securing a hose connection, in particular a plug-in connection of a hose, with a second hose clamp bracket of the same type, comprising: a locking projection region; a locking projection receiving region; and a bracket region arranged between the locking projection region and the locking projection receiving region and substantially semi-annular in shape, the curved inner surface of which bracket is intended to bear against an outer surface of a hose; wherein the locking projection region comprises an outwardly extending locking projection at its end; wherein the locking projection receiving region is arranged opposite the locking projection and has an elongated groove on its inner side for receiving a locking projection region of a second hose clamp bracket, in particular a second hose clamp bracket of the same type;and wherein the locking projection receiving area in the elongated groove has a locking projection receptacle for locking a locking projection of the second hose clamp bracket.;

[0007] Advantageously, such a hose clamp bracket can provide a hose clamp that allows media, such as fluids, to be securely directed from a connector into a hose and vice versa. The hose clamp bracket according to the invention helps ensure that the hose can be pressed tightly onto the connector and, in addition, that a certain degree of pull-off force can be ensured between the hose and the connector.

[0008] Furthermore, the hose clamp bracket according to the invention advantageously makes it possible to provide a hose clamp for securing a hose connection that can ensure a defined closing force. In contrast to a cable tie, a hose clamp bracket according to the invention is force-controlled and not displacement-controlled.

[0009] A further advantage is that a hose clamp bracket according to the invention can be applied from the outside to a hose and the hose connection point to be secured, and can be clipped to a second, identical hose clamp bracket to secure the hose connection. A hose clamp bracket according to the invention, and thus a hose securing device, can be precisely positioned. The hose clamp bracket according to the invention, and the hose clamp it provides, offer particular advantages when connecting a thermoplastic connector and a silicone hose, since this material combination cannot be fixed with adhesive.

[0010] Furthermore, a hose clamp bracket according to the invention can be provided simply, quickly, compactly and inexpensively.

[0011] The hose clamp bracket can be designed specifically for a hose clamp to secure a plug-in connection of a hose. With a plug-in connection, the hose is attached to a hose connection or connector, such as a nozzle.

[0012] In particular, the invention relates to hose connections in the field of medical technology and / or pharmaceuticals. However, the invention is not limited to such hose connections. The invention also relates to hose connections in coffee machines.

[0013] In the context of this description, the term “same type” means that the second hose clamp bracket can have largely similar features to the hose clamp bracket according to the invention or can even have the identical shape and size to the first hose clamp bracket according to the invention.

[0014] For the purposes of this description, the term "essentially semi-annular" includes deviations from the exact semi-annular shape and manufacturing tolerances. The bracket area can therefore also be bent in a U-shape. The bracket area has a radius of curvature. The radius of curvature can be constant or variable. The hose clamp bracket can be U-shaped or horseshoe-shaped.

[0015] For the purposes of this description, the term "inside" refers to areas of the hose clamp bracket that face the outer surface of a hose when securing a hose connection. In other words, the term "inside" refers to the area surrounded or delimited by the locking projection area, the bracket area, and the locking projection receiving area. This area is further delimited by an imaginary line between the two ends of the hose clamp bracket.

[0016] The term "outside" refers to areas of the hose clamp bracket that are facing away from the imaginary center of the semi-circular bracket area and / or that are facing away from the outer surface of the hose when securing the hose connection. In other words, the term "outside" refers to the area not surrounded or delimited by the locking projection area, the bracket area, the locking projection receiving area, and the imaginary line between the two ends of the hose clamp bracket.

[0017] The hose clamp bracket is preferably formed in one piece. The locking projection area, the bracket area, and the locking projection receiving area can merge seamlessly into one another. They can be indistinctly separated from one another. They can also be formed offset from one another.

[0018] The hose clamp bracket can also be made up of several pieces.

[0019] The locking projection can be arranged, in particular, at one of the two outer ends of the hose clamp bracket, which is encompassed by the locking projection region. The locking projection receiving region can comprise the other outer end of the hose clamp bracket, at which the locking projection receptacle can be arranged.

[0020] The elongated groove can extend between the bracket portion and the outer end of the hose clamp bracket encompassed by the locking projection receiving portion. The elongated groove can run between the bracket portion and the outer end of the hose clamp bracket encompassed by the locking projection receiving portion. The elongated groove can be an elongated recess in the locking projection receiving portion. The locking projection receptacle can be a recess in the elongated groove.

[0021] The locking projection area can extend straight or curved, in particular from the bracket area.

[0022] The locking projection area, the curved inner surface of the bracket area and the elongated groove of the locking projection receiving area, including their locking projection receptacle, lie in particular in the same plane, namely the plane of symmetry of the hose clamp bracket.

[0023] This ensures that two hose clamp brackets of identical shape and size can be assembled to form one hose clamp and can be locked with their locking projections into the locking projection receptacle of the other hose clamp bracket.

[0024] According to one embodiment of the hose clamp bracket, the inner surface of the bracket area has a profile.

[0025] Due to the profiling, a force caused by the design of the profiling can be exerted on a hose and compress it or press it against a hose connection if the hose clamp bracket is arranged on the hose together with a second hose clamp bracket of the same type in order to secure the connection between the hose and the hose connection.

[0026] The profiling can also give the hose clamp bracket dimensional stability.

[0027] The profiling may comprise a rib extending longitudinally along the bracket area. Additionally or alternatively, the profiling may comprise one or more teeth arranged along the bracket area.

[0028] The thickness and / or height of the rib determines the force exerted on the hose. The rib and / or teeth allow the hose clamp to further grip the outer surface of the hose, ensuring that the hose clamp is securely positioned.

[0029] The rib may have a stop at each of its ends in the longitudinal direction. The stop may be beveled.

[0030] According to one embodiment of the hose clamp bracket, the bracket region, in particular in a central region of the bracket region, has a widening of its outer surface with respect to its inner surface.

[0031] The widened section allows a tool, such as a toggle press, to be used when installing the hose clamp bracket. The widened section makes the hose clamp bracket more resistant to external forces.

[0032] The widened outer surface can extend substantially perpendicular to a plane spanned by the hose clamp bracket, in which the curvature of the bracket area lies. Additionally, the widened portion can be spherical shell-shaped.

[0033] According to one embodiment of the hose clamp bracket, the locking projection is nose-shaped, in particular as a snap hook or locking bar, and extends outwards from the end of the locking projection area.

[0034] This design of the locking projection enables particularly simple and secure locking of two similar hose clamp brackets. In particular, the locking projection can be pushed through the groove with little resistance toward the locking projection receptacle of a second hose clamp bracket of the same type.

[0035] The locking projection can protrude outwards from the end of the locking projection region. The front side of the locking projection can be flat or rounded. The front side can be delimited by four side surfaces. The locking projection can taper outwards along at least one of its side surfaces. The front side of the locking projection can comprise a nose region and a front region. The nose region can be flat or rounded. The front region can be inclined with respect to the longitudinal extent of the locking projection region. The front region can be rounded or curved. A side surface of the locking projection arranged next to the front side of the locking projection in the direction of the bracket region can be designed as a locking step in order to engage with and / or strike against a locking step of a second hose clamp bracket of the same type.

[0036] Additionally or alternatively, the locking projection receptacle is arranged at an end of the locking projection receptacle region opposite the locking projection and / or arranged facing the locking projection region.

[0037] This design of the locking projection holder enables particularly simple and safe rusting of two similar hose clamp brackets.

[0038] According to one embodiment of the hose clamp bracket, the locking projection receiving area is essentially block-shaped.

[0039] The block shape of the locking projection receiving area increases the stability of the hose clamp bracket in this area. Furthermore, the load-bearing capacity of the hose clamp bracket against forces acting on the locking projection receiving area can be increased.

[0040] The locking projection receiving area can in particular be cuboid-shaped.

[0041] According to one embodiment of the hose clamp bracket, the groove has a width that approximately corresponds to the width of the locking projection area or is greater than the width of the locking projection area. This allows for easy insertion of a locking projection area, in particular a locking projection, of a second hose clamp bracket of the same type into the groove and thus into the locking projection receiving area.

[0042] When a second hose clamp bracket with its locking projection is inserted, it is safely guided into the groove and held there.

[0043] Additionally or alternatively, the groove has a depth that decreases in the direction of the locking projection receptacle and / or in the direction of the bracket area.

[0044] By reducing the depth, it can be prevented that a locking projection area and in particular a locking projection of a second hose clamp bracket of the same type can detach itself from the locking projection receptacle and slip out of the locking projection receptacle area.

[0045] Additionally or alternatively, the groove has a raised portion in front of the locking projection receptacle, which forms a step-like boundary, in particular a locking step, of the locking projection receptacle.

[0046] When a second hose clamp bracket with its locking projection is inserted into the groove from the side of the block-shaped locking projection receiving area facing away from the bracket area, the locking projection slides through the groove and is initially compressed by the depth reduced in the direction of the bracket area and / or by the elevation in front of the locking projection receiving area before the locking projection engages in the locking projection receiving area.

[0047] A corresponding locking step of a locking projection of a second hose clamp bracket of the same type can rest or abut against the stepped boundary or locking step of the elevation, thus ensuring reliable locking of the locking projection of the second hose clamp bracket of the same type on or in the locking projection receptacle. The elevation further prevents the locking projection area, and in particular the locking projection of the second hose clamp bracket of the same type, from disengaging itself from the locking projection receptacle and slipping out of the locking projection receptacle area.

[0048] The stepped boundary of the elevation can be a substantially vertical wall that defines the locking projection receptacle. This wall can, in particular, run perpendicular to the longitudinal extension of the groove.

[0049] Furthermore, the locking projection receptacle can be designed as a recess in the groove, in particular downstream of the elevation.

[0050] According to one embodiment of the hose clamp bracket, the hose clamp bracket is molded from a plastic material. The hose clamp bracket can, in particular, be manufactured using an injection molding process.

[0051] This makes it possible to produce the hose clamp bracket easily, quickly, cost-effectively and in large quantities.

[0052] According to one embodiment of the hose clamp bracket, the bracket area and / or the locking projection area is / are designed to be resilient in the direction of reducing the distance between the locking projection and the locking projection receiving area.

[0053] This ensures that the locking projection area can still be easily inserted into the groove of the second hose clamp bracket, even with minor manufacturing deviations, for example, regarding the position and / or depth of the groove of the locking projection receiving area of ​​the second hose clamp bracket. The position of the locking projection area can be adapted to a certain extent to the position and design of the groove of the locking projection receiving area of ​​the second hose clamp bracket.

[0054] Additionally or alternatively, the bracket area and / or the locking projection area is designed such that after compression in the direction of reducing the distance between the locking projection and the locking projection receiving area, the locking projection moves back to its initial position.

[0055] The locking projection can, for example, be deflected from its initial position when inserted into the groove of a second hose clamp bracket of the same type and, after passing through the groove, return to the initial position in order to move into the locking projection receptacle of the second hose clamp bracket and lock into it.

[0056] By moving back to the starting position, it can be ensured that the locking projection area or the locking projection cannot be removed from the groove or the locking projection receptacle of the second hose clamp bracket without being compressed again.

[0057] A further, in particular second, aspect of the invention relates to a hose clamp for securing a hose connection, in particular a plug-in connection of a hose, comprising: two hose clamp brackets according to the preceding aspect or one of its embodiments, which comprise a first hose clamp bracket and a second hose clamp bracket, wherein the two hose clamp brackets are connected to one another in that their locking projection areas are at least partially received in the elongated groove of the respective other hose clamp bracket and in that their locking projections are each locked in the locking projection receptacle of the respective other hose clamp bracket.

[0058] Advantageously, the hose clamp according to the invention can be used to secure a hose connection in a particularly stable, reliable and easily positionable manner.

[0059] Since two identical hose clamp brackets are required for the hose clamp, only one version of the hose clamp bracket needs to be manufactured and / or stored. The hose clamp is universally applicable and depends solely on the diameter of the hose to be secured. The hose clamp can be attached after the hose has been connected to a hose connector and does not need to be pushed or pushed onto the hose up to the connection point prior to assembly to secure the hose connection. Furthermore, the hose clamp can be installed in a qualified and reproducible manner.

[0060] The description made with respect to the inventive aspect of the hose clamp bracket, including embodiments, individual features and advantages, can be applied and transferred to the inventive aspect of the hose clamp.

[0061] According to one embodiment of the hose clamp, the two hose clamp brackets are connected to each other in such a way that they cannot be separated from each other without tools.

[0062] This ensures a very strong and stable securing of a hose connection, as the two hose clamp brackets cannot be separated from each other with bare hands.

[0063] According to one embodiment of the hose clamp, the two hose clamp brackets have the same size and shape.

[0064] This has the advantage that one does not have to produce different parts for the hose clamp according to the invention, which would make the production of the hose clamp more complex.

[0065] The two hose clamp brackets can be of identical shape and size. This allows the two hose clamp brackets of one hose clamp to be manufactured cost-effectively.

[0066] According to one embodiment of the hose clamp, the first hose clamp bracket is rotated approximately 180° relative to the second hose clamp bracket. Preferably, the rotation is perpendicular to the plane in which the bracket portion of the second hose clamp bracket is bent or in which the bend of the bracket portion of the second hose clamp bracket extends.

[0067] As already mentioned above, a hose clamp according to the invention only requires two identical hose clamp brackets that are twisted relative to each other and locked together.

[0068] The hose clamp can have a gap between the locking projection area, in particular the locking projection, of the first hose clamp bracket and the locking projection receiving area and / or the bracket area of ​​the second hose clamp bracket. The hose clamp can additionally or alternatively have a gap between the locking projection area, in particular the locking projection, of the second hose clamp bracket and the locking projection receiving area and / or the bracket area of ​​the first hose clamp bracket.

[0069] The hose clamp can be used in medical and / or pharmaceutical systems. For example, the hose clamp can be used to secure a pump hose to a pump housing. However, the hose clamp's use is not limited to medical and / or pharmaceutical systems. It can also be used to secure hose connections in coffee machines.

[0070] A further, particularly third, aspect of the invention relates to a hose connection, in particular a plug-in connection of a hose, which is secured in a radial plane by means of a hose clamp according to the preceding aspect or one of its embodiments; wherein the first and second hose clamp brackets on the hose connection are arranged on opposite regions of the outer surface of the hose approximately in the same radial plane, and the inner surfaces of the bracket regions rest against the outer surface of the hose;wherein the locking projection of the first hose clamp bracket is locked in the locking projection receptacle of the elongated groove of the locking projection receptacle area of ​​the second hose clamp bracket, and the locking projection of the second hose clamp bracket is locked in the locking projection receptacle of the elongated groove of the locking projection receptacle area of ​​the first hose clamp bracket, so that the hose connection is pressed together by the bracket areas of the two hose clamp brackets in a radial plane and thus secured.;

[0071] The description made with respect to the preceding aspect of the hose clamp, including embodiments, individual features and advantages, can be applied and transferred to the inventive aspect of the hose connection.

[0072] The term “radial plane” refers here to the hose to be secured, which has a circular cross-section.

[0073] According to one embodiment of the hose connection, the profiling, in particular the rib and / or teeth, of the inner sides of the bracket areas engages in the outer surface of the hose connection and thus additionally secures it.

[0074] A further, in particular fourth, aspect of the invention relates to a method for securing a hose connection, in particular a plug-in connection of a hose, with two hose clamp brackets according to the first aspect of the invention or one of its embodiments, comprising the following method steps: arranging a first hose clamp bracket on a hose connection, in particular a plug-in connection of a hose, such that the curved inner surface of its bracket region rests against the outer surface of the hose; arranging the second hose clamp bracket on the hose connection on the opposite region of the outer surface of the hose approximately in the same radial plane, such that the locking projection region of the second hose clamp bracket lies in the direction of the elongated groove of the first hose clamp bracket and the locking projection region of the first hose clamp bracket lies in the direction of the elongated groove of the second hose clamp bracket;Locking the locking projection of the first hose clamp bracket in the locking projection receptacle of the elongated groove of the locking projection receptacle area of ​​the second hose clamp bracket, by inserting the locking projection of the first hose clamp bracket into the groove, in particular via a raised portion in the groove, of the locking projection receptacle area of ​​the second hose clamp bracket and by resiliently compressing the locking projection area to the locking projection receptacle area of ​​the first hose clamp bracket;and locking the locking projection of the second hose clamp bracket in the locking projection receptacle of the elongated groove of the locking projection receptacle area of ​​the first hose clamp bracket, by inserting the locking projection of the second hose clamp bracket, in particular via a raised portion in the groove, of the locking projection receptacle area of ​​the first hose clamp bracket and by resiliently compressing the locking projection area to the locking projection receptacle area of ​​the second hose clamp bracket.

[0075] The two hose clamp brackets are arranged in particular in such a way that the second hose clamp bracket is rotated by approximately 180° relative to the first hose clamp bracket, that their curved inner surfaces of their bracket areas enclose the outer surface of the hose, and that their locking projections are each locked in the locking projection receptacle of the other hose clamp bracket.

[0076] This method ensures a stable, reliable, simple and cost-effective securing of a hose connection.

[0077] In addition, a hose clamp according to the second aspect of the invention or one of its embodiments can be assembled in a qualified and reproducible manner.

[0078] Furthermore, the description made with regard to the inventive aspect of the hose clamp bracket, including embodiments, individual features, and advantages, can be applied to and transferred to the inventive aspect of the method. According to one embodiment of the method, the locking of the locking projection of the first hose clamp bracket in the locking projection receptacle of the elongated groove of the locking projection receptacle region of the second hose clamp bracket and the locking of the locking projection of the second hose clamp bracket in the locking projection receptacle of the elongated groove of the locking projection receptacle region of the first hose clamp bracket take place simultaneously and, in particular, with the assistance of a tool.

[0079] All other process steps can be performed sequentially in the following order: The first hose clamp bracket can be positioned first, followed by the second hose clamp bracket, or vice versa. The hose clamp brackets can then be locked together.

[0080] Additionally or alternatively, the hose connection is compressed in a radial plane by the bracket areas of the two hose clamp brackets and thus secured.

[0081] According to one embodiment of the method, the profiling, in particular the rib and / or teeth, of the inner sides of the bracket areas engages in the outer surface of the hose connection and thus additionally secures it.

[0082] In the following, embodiments of the present invention are explained in detail with reference to the accompanying figures.

[0083] Figure 1 shows a longitudinal sectional view of an embodiment of the hose clamp bracket according to the invention;

[0084] Figure 2 shows a perspective view of the embodiment of the hose clamp bracket according to the invention shown in Figure 1;

[0085] Figure 3 shows a further perspective view of the embodiment of the hose clamp bracket according to the invention shown in Figure 1; Figure 4 shows a plan view of the embodiment of the hose clamp bracket according to the invention shown in Figure 1;

[0086] Figure 5(a) shows a front view of an embodiment of a hose clamp according to the invention;

[0087] Figure 5(b) shows a perspective view of the embodiment of the hose clamp according to the invention shown in Figure 5(a);

[0088] Figure 6 shows the hose clamp of Figure 5(b) mounted on a hose to secure the hose connection; and

[0089] Figure 7 shows a cross-section through the hose connection shown in Figure 6 and shows the locking of the hose clamp brackets.

[0090] Figure 1 shows a longitudinal sectional view of a hose clamp bracket 10A. The hose clamp bracket 10A runs or extends between its two opposite, outer ends 121A and 167A, and is curved or bent. The locking projection region 12A extends from one end 121A. The locking projection 122A is arranged at the end 121A, which is also the end of the locking projection region 12A. This extends outward from the locking projection region 12A in a direction that runs from the end 167A to the end 121A. The locking projection 122A has a front side 123A running perpendicular to the plane of the drawing in Figure 1. This is divided into a flattened nose region 124A and a flat front region 125A located between the nose region 124A and the end 121A.The end region 125A is formed obliquely or inclined relative to the nose region 124A in order to facilitate insertion of the locking projection 122A into the locking projection receptacle of a second hose clamp bracket. Adjacent to the nose region 124A and running perpendicular to it, a locking step 126A is formed on the locking projection 122A. From the locking projection 122A, the locking projection region 12A extends, in particular slightly inclined or curved inward towards the end 167A, and merges into the bracket region 14A without a sharp demarcation. The bracket region 14A is curved in the direction from the locking projection region 12A towards the end 167A. On its curved inner surface 141A, the bracket region 14A has a rib 142A which extends with its longitudinal extent along the bracket region 14A. The rib 142A extends from a transition region between the locking projection region 12A and the bracket region 14A towards the end 167A.

[0091] Further towards the end 167A, the bracket region 14A merges seamlessly into the locking projection receiving region 16A. The rib 142A extends into a transition region between the bracket region 14A and the locking projection receiving region 16A. The locking projection receiving region 16A has a cuboid shape and has on its inner side 161A, i.e. on the side facing the locking projection region 12A, an elongated groove 162A which extends from the end 167A of the locking projection receiving region 16A or hose clamp bracket 10A towards the bracket region 14A. At the bracket region-side end 164A of the groove 162A or of the locking projection receiving region 16A, the groove 162A has a recess 163A. The recess functions as a locking projection receptacle 163A for receiving a locking projection of another hose clamp bracket. Along the groove 162A toward the end 167A of the hose clamp bracket 10A, the recess 163A is delimited by a wall 166A.This wall acts as a locking step 166A, against which the locking step of a locking projection of another hose clamp bracket can engage and lock. The groove 162A further has a raised portion 165A in front of the locking projection receptacle 163A in the direction of the locking projection receptacle 163A and defined by the wall or locking step 166A, which reduces the depth of the groove 162A.

[0092] The elevation 165A extends in the groove 162A from the locking projection receiving area 16A towards the locking projection area 12A. Along the groove 162A towards the locking projection receptacle 163A, the elevation 165A increases at a constant gradient and then flattens out. The elevation serves to elastically deform the locking projection area or the locking projection of a hose clamp bracket as it is inserted and passed through the groove 162A, or to deflect it from its equilibrium position. After passing the elevation 165A, the locking projection of the inserted locking projection area can relax into its equilibrium position and snap into the locking projection receptacle 163A. This ensures additional security, since the locking projection area of ​​the inserted hose clamp bracket cannot detach itself from the locking projection receiving area 16A.

[0093] In the perspective view of the hose clamp bracket 10A in Figure 2, it can be seen that the hose clamp bracket 10A in Figure 1 has a widening 144A of the curved outer surface 143A of the bracket area 14A. Coming from the locking projection area 12A, the outer surface of the hose clamp bracket 10A widens in the area of ​​the bracket area 14A to approximately the thickness of the locking projection receiving area 16A.

[0094] In the perspective view of the hose clamp bracket 10A in Figure 3, it can be seen that the inner surface 141A of the bracket area 14A also widens corresponding to the outer surface 143A, coming from the locking projection area 12A in the direction of the locking projection receiving area 16A. It can also be seen that the rib 142A has stops 145A at its ends in the longitudinal direction, which are designed to bear against corresponding stops of a hose clamp bracket locked to the hose clamp bracket 10A, thus ensuring greater stability when securing a hose connection.

[0095] As in Figure 2, Figure 3 also shows that the groove 162A forms a tunnel in the transition region between the bracket region 14A and the locking projection receiving region 16A between the stop 145A of the rib 142A and the locking projection receptacle 163A and runs in a tunnel shape. The tunnel region of the groove 162A extends approximately from the beginning of the elevation 165A to the locking projection receptacle 163A. Figure 4 shows a plan view of the hose clamp bracket 10A shown in Figures 1 to 3, looking onto the inner surface 141A of the bracket region 14A. Furthermore, Figure 4 provides a clear view into the groove 162A of the locking step 166A in the locking projection receptacle 163A. Figure 4 also shows that the width of the outer surface of the hose clamp bracket decreases from the locking projection receiving area 16A, through the bracket area 14A, to the locking projection area 12A. The width of the locking projection area 12A is approximately the same size as or smaller than that of the groove 162A.The width of the inner surface of the hose clamp bracket 10A also decreases from the locking projection receiving area 16A through the bracket area 14A to the locking projection area 12A. However, it can be seen that the width of the inner surface decreases more rapidly than that of the outer surface. The inner surface 141A of the bracket area 14A has a substantially smaller width than the outer surface 143A of the bracket area 14A.

[0096] Figures 5(a) and 5(b) show, on the one hand, a frontal view of a hose clamp 1000 and, on the other hand, a perspective view of the hose clamp 1000. The hose clamp 1000 shown consists of two hose clamp brackets 10A and 10B of identical shape and size, which are locked together and can thus secure a hose connection (see Figures 6 and 7). Figure 5(a) shows that the stops 145A, 145B of the ribs 142A, 142B can be inclined or beveled.

[0097] Figures 5(a) and 5(b) show that the locking projections 122A, 122b of the hose clamp brackets 10A, 10B protrude from the respective locking projection receiving area 16B, 16A when the hose clamp 1000 is locked. This ensures that the locking can be released from the outside if necessary.

[0098] In Figure 6, the hose clamp 1000 shown in Figures 5(a) and 5(b) is mounted on a hose S, which is plugged onto a hose connection designed as a nozzle T in order to secure the plug-in connection between hose S and nozzle T. Figure 7 shows a cross-sectional view through the hose connection shown in Figure 6 with hose clamp 1000. In Figure 7, the view of the hose clamp 1000 is directed away from the hose connection T.
