Description

Anti-theft device

The present invention relates to a device for mechanically securing goods against theft, the device comprising a first holding part with a fastening surface for fastening to an object, a second holding part for fastening to the goods, a cable connecting the two holding parts and the Holding parts each have associated connecting parts with undercut sections for producing a releasable, form-fitting holding connection of the two holding parts.

Such security devices are used above all in shops for radio and television sets, video equipment, telephone systems or the like, in which a large number of exhibition devices are ready for use and ready for use by customers for testing purposes. In order to avoid loss of the devices or in particular remote controls assigned to them, the smaller devices or the remote controls are attached to an object, such as an exhibition shelf or a large, unwieldy device, using the devices mentioned. The cable connecting the two holding parts allows the customer to test use the secured device or the secured goods. The connection to the object makes it difficult to steal the goods.

The connecting parts provided on the securing device allow a holding connection to be made between the two holding parts. This makes it possible to Secure goods releasably connected to the assigned object for an attractive presentation.

A device for mechanically securing a product against theft with the features mentioned at the outset is known, in which two holding parts are connected to one another via a thin plastic cable. On the side of the holding parts facing away from the object or the goods to be secured, connecting parts are arranged, which are formed on the one hand by a web with a dovetail cross section and on the other hand by a complementary groove which is open on one end face. To produce the holding connection between the holding parts, the web-like connecting part can be inserted longitudinally into the recess and parallel to a fastening surface of the holding part to be fastened to the object.

The disadvantage here is that the production of the holding connection requires a relatively precise insertion of the web-like connecting part into the recess. It should also be taken into account that the entire device is often covered by the goods to be secured when the holding connection is made. This results in the further disadvantage that a customer tries to release the holding connection, in particular when the first holding part is attached to a vertically running surface of an object, to pick up the goods with a force directed away from the surface of the object, as a result of which the first holding part, which is usually stuck to the object, is very easily torn off the object. Accordingly, the known device does not withstand frequent use. Furthermore, a device for mechanically securing a product against theft is known, in which the two holding parts are connected to one another via a thin steel strand. The device has connecting means for producing a releasable holding connection, which are formed by so-called Velcro fasteners, which are each arranged on the side of the holding parts facing away from the object or the goods to be secured.

The disadvantages here are that loosening the Velcro connection between the holding parts requires a considerable release force, which can lead to impairment of the connection between the holding part and the goods or the object to be secured if the device is used frequently , and that the Velcro fasteners do not specify a defined relative position of the two holding elements in their connected state relative to one another, whereby the production of a correct holding connection between the holding parts is particularly difficult for the customer, which leads to damage to the secured goods by can lead to unwanted loosening of the holding connection. In addition, the Velcro connection is not very resilient.

The invention has for its object to provide a device for mechanically securing goods against theft, which enables particularly simple handling and the establishment of a secure holding connection.

This object is achieved according to the invention in a device having the features mentioned at the outset in that at least one of the connecting parts has an undercut section with an inclined portion in relation to the fastening surface Run-up surface comprises that the holding connection can be released by means of a release force acting perpendicular to the mounting surface.

Because of the design according to the invention, it is possible to fasten the first holding part to a vertically extending surface of an object in such a way that the relative movement of the second holding part relative to the first, which is required to release the holding connection, runs obliquely upwards with respect to the horizontal. Accordingly, the weight of the second holding part and a product held by it counteracts an unwanted loosening of the holding connection between the holding parts, since the weight causes a force component opposite to the loosening movement due to the inclined contact surface. Furthermore, this arrangement complies with the intuitive behavior of the customer to move the goods directly away from the object. The solution according to the invention namely leads to a force component in the direction of the inclination of the run-up surface which results in the case of a releasing force acting on the second holding part in the direction of the surface normal of the fastening surface of the first holding part, that is to say a force component in the direction of the inclination of the run-up surface which results in egg ¬ leads in this direction releasing movement of the second holding part with respect to the first. Accordingly, the holding connection is released very easily, even if the entire device should be covered by the goods to be secured when the holding connection is made to the object.

In a preferred embodiment, the inclination angle enclosed by the run-up surface and the fastening surface is 25 to 60 °. This provides good protection against deliberate loosening of the holding connection, for example if a customer accidentally encounters a product held by the securing device, and moreover a relatively easy loosening of the holding connection with this inclination range, the connection of the first holding part to the object not being overloaded.

A particularly preferred embodiment is characterized in that the undercut sections are each arranged at edge regions of the connecting parts in such a way that the holding connection can be produced by a relative movement of the holding parts running essentially parallel to the fastening surface. This results in a very simple production of the holding connection in that the second part can be attached to the first holding part by a movement which is essentially parallel to the surface of the object. In addition, the holding connection can be loosened both in the direction of the inclination of the run-up surface and counter to the above-mentioned suspension direction, so that the loosening of the holding connection is simplified.

A very heavy-duty holding connection results from the fact that one of the connecting parts comprises two undercut run-up surfaces, the planes of which have track straight lines running at an angle to one another in the plane of the fastening surface. In the case of an approximately vertical alignment of the angle half ends between the track straight lines, a holding connection which is particularly strong due to tilting moments is made possible, whereby the two connecting parts engage behind one another in particular over the entire longitudinal extent of the contact surfaces. In a variant, the V-shape is modified in that it is flattened in the area of its tip, so that three undercut ramp surfaces are formed. As a result, sharp corners and edges are largely avoided, so that there is no risk of injury even if they protrude.

A particularly preferred embodiment variant provides that the two contact surfaces are arranged in a V-shape with respect to one another. Thus, the run-up surfaces for the complementary connecting part form an insertion bevel, which further facilitates the production of the holding connection.

The cutting angle of the track straight is preferably 50 to 80 °. This leads to a very tilt-stable, but also easily detachable holding connection between the holding parts.

A particularly simple manufacture of the device results from the fact that the connecting parts are each formed in one piece with the holding parts. Alternatively, however, the connecting parts can also be manufactured separately from the holding parts and subsequently arranged on the latter.

A particularly preferred embodiment is characterized in that the connecting parts are essentially rigid. In addition to simple manufacture, this results in a particularly high load-bearing capacity of the holding connection, since the connecting parts are not flexible. In addition, there is a very long service life of the device, even if the device is used frequently, since fatigue of for example, when producing and releasing the holding connection, elastically deformed sections are omitted.

The fact that the second holding part comprises a fastening surface for fastening to the goods and the fastening surfaces of the two holding parts are parallel and facing away from one another when the holding connection is produced means that the surfaces of the goods and the object to which the holding parts are attached by means of of the fastening surfaces are always parallel to one another when the holding connection is established. This results in a uniform alignment of the secured goods when the holding connection is made. This is conducive to an attractive presentation of the goods.

Another alternative embodiment results from the fact that the connecting parts are designed so that the holding parts can be locked together. This can be achieved, for example, in that the connecting parts comprise at least one resilient, undercut section. The latched holding part has the advantage that an unwanted loosening of the holding connection, for example if a customer accidentally bumps into the secured goods, is largely avoided. The frequency of damage to the goods is thus reduced.

In a further embodiment variant, it is provided that a connecting part comprises edge sections which overlap the other connecting part on several sides with lateral play when the holding connection is produced. This enables the production of a holding connection between the connecting parts even at different rotational positions of the securing device. Lateral play is required in order to G

undercut sections to allow easy production and release of the holding connection.

The invention is explained in more detail below with reference to the drawing of three exemplary embodiments. Show it:

1 shows a device 10 according to the invention for mechanically securing a product (not shown) against theft. The device 10 comprises a first holding part 12 and a second holding part 14, which are connected to one another with a cable 16 in the form of a flexible, partially helix-like plastic cable. !

2 shows that the two holding parts 12 and 14 each have essentially the shape of a flat cuboid.

The first holding part 12 is provided for attachment to an object, such as a larger device, a goods shelf or the like. For this purpose, the first holding part 12 comprises, on a flat side, a fastening surface 18 on which an adhesive layer 20 is glued, as can be seen in FIG. 1.

Likewise, the second holding part 14 has, on a flat side, a fastening surface 18 with an adhesive layer 20, which serves to fasten a product, not shown, to be secured.

In the exemplary embodiment, the adhesive layer 20 is formed in each case by a double-sided adhesive tape.

The first holding part 12 has a first connecting part 22 on its flat side facing away from the fastening surface 18. This is formed in one piece with the holding part 12.

The first connecting part 22 has essentially the shape of a flat cuboid, the connecting part 22 merging into the first holding part 12 on a flat side.

Since both the first holding part 12, the second holding part 14 and the first connecting part 22 are each formed essentially in the shape of a flat cuboid in the exemplary embodiment shown, the narrow sides of the cuboid shape are uniformly designated by a, b, c and d , where a / O

and c denote the long sides and b and d denote the top sides of the cuboids, as can be seen in FIG. 2.

The sides of the first connecting part 22 are arranged parallel to the corresponding sides of the first holding part 12 with their sides a to d. Starting from the peripheral edge 24 of the flat side of the connecting part 22 facing away from the first holding part 12, the latter has an insertion bevel 26 on its sides a, b and c, so that the connecting part 22 on the sides a, b and c in the direction for holding part 12 widened like a truncated pyramid. This is followed on the three sides a, b and c of the connecting part 22 by an undercut section 28 which forms a common edge 30 with the insertion bevel 26 on the sides a, b and c. A straight section 32 with a constant rectangular cross section adjoins the undercut section up to the first holding part 12. The insertion bevel 26 and the sections 28 and 32 are formed on each of the sides a, b and c by flat surface sections. The head side 22d of the first connecting part 22 facing the connecting cable 16 runs perpendicular to the fastening surface 18 of the first holding part 12.

The second holding part 14 has a second connecting part 34 which, in the exemplary embodiment shown, is formed by a recess which essentially has the shape of a flat cuboid on the side of the second holding part 14 which faces away from the fastening surface 18. This cuboid recess and thus the second connecting part 34 is essentially complementary to the first connecting part 22. The sides a to d of the cuboid shape again run parallel to the corresponding sides of the cuboid formed by the second holding part 14.

The second connecting part 34 comprises an edge section 36 which delimits the recess formed on all sides a to d. The edge section 36 has an inner circumferential edge 38 at the free end facing away from the fastening surface 18 of the holding part 14. Starting from this edge 38, the edge section 36 has a straight wall section 40 on its inner wall on all sides a to d, which runs perpendicular to the fastening surface 18. This is followed by an undercut section 42, which is formed on the sides a, b and c of the inner wall of the edge section 36 and of the second connecting part 34. This undercut section 42 corresponds in its inclination and extent essentially to the undercut section 28 of the first connecting part 22. The undercut section 42 leads to an increase in the clear cross section in the direction of the fastening surface 18 of the second holding part 14.

The undercut section 42 is adjoined by an oblique section 44, which has an opposite inclination and is correspondingly formed on the sides a, b and c. Sections 42 and 44 have a common edge 46 on sides a, b and c. With its opposite edge, the section 44 merges into the bottom 48 of the recess formed by the second connecting part 34. This runs parallel to the fastening surface 18 of the holding part 14.

The inner side 36d of the edge section 36 adjacent to the cable 16 corresponds to the head side 22d of the first Connecting part 22 running vertically to the mounting surface 18 and flat.

In the illustrated embodiment, the undercut sections 28, 42 as well as the insertion bevel 26 and section 44 are each inclined essentially at the same angle. However, different inclinations, which can also vary depending on the sides a, b, c, can also be provided.

The mutual adaptation of the two connecting parts 22 and 34 is explained below with reference to FIGS. 1 and 2. 2 shows a plan view of the second holding part 14 connected to the first holding part 12. The edges of the two connecting parts 22 and 34 which are essential for the spatial adaptation are shown in broken lines. The establishment of the connection will be described in detail later.

The edge 30, which extends over the three sides a, b and c of the first connecting part 22, together with the head side 22d, forms the largest cross section of the protruding first connecting part 22. The second connecting part 22, on the other hand, has a minimal one which is enlarged by a small margin open cross-section in the area of the edge 38 of the edge section 36 and in the area of the wall section 40. Since, in addition, the depth of the recess formed by the second connecting part 34 is adapted to the height of the protruding first connecting part 22, that is to say the two connecting parts 22 and 34 correspond in their respective extent perpendicular to the fastening surfaces 18, it is possible that fully insert the first connecting part 22 into the second connecting part 34. '3

The establishment of the holding connection between the two holding parts 12 and 14, that is to say the arrangement of a product to be secured to the second holding part 14 by means of the adhesive layer 20, on an object carrying the first holding part 12 by means of the associated adhesive layer 20 , takes place by a movement in the direction of arrow 50 which is essentially perpendicular to the fastening surfaces 18. The two fastening surfaces 18 and thus the two holding parts 12 and 14 are oriented essentially parallel to one another. When the second holding part 14 is moved toward the first holding part 12, the insertion bevel 26 of the first connecting part 22 and the edge 38 of the second connecting part 34 abutting there causes an automatic centering or relative alignment of the second holding part 14 with the first holding part 12. When the holding part 14 is brought closer to the holding part 12, the straight section 40 of the second connecting part 34 slides over the edge 30 and the head side 22d of the first connecting part 22. Since there is a certain play between the two connecting parts 22 and 34, the holding connection is made smoothly. Finally, the free end of the edge section 36 of the second connecting part 34 abuts the first holding part 12 and limits the movement in the direction of the arrow 50.

The frequently occurring case that the first connecting part 12 is glued to a vertically extending surface of the object (not shown) with its adhesive layer 20 and is oriented here in such a way that the side b lies above and runs horizontally is described below. After the above-described joining of the two holding parts 12 and 14, so that the edge section 36 of the second connecting part 34 overlaps the projecting first connecting part 22 on all sides, the weight causes the second holding part 14 to be displaced with respect to the first holding part 12 according to arrow 52 downward. This means that the undercut sections 28 and 42 engage behind in the region of the upper side b and the side b of the inner wall formed by the edge section 36 comes to rest on the head side b of the first connecting part 22. This results in a positive connection between the two holding parts 12 and 14, which is also very resilient due to the rigid design of the two connecting parts 22 and 34. The second holding part 14 is thus suspended on the first. The engagement of the two undercut sections 28 and 42 prevents the second connecting part 34 from sliding off the first connecting part 22 against the direction of the arrow 50. This results in a secure holding connection between the two holding parts 12 and 14, which is secured against unwanted loosening.

An essential idea of the invention is to be seen in the fact that the undercut section 28 and the undercut section 42 each form a run-up surface 54 which runs obliquely to the direction of the arrow 50, that is to say obliquely to the direction of movement for the production of the holding connection, in the region of the upper Side b has a surface normal 56 with a vertical component. This alignment of the two undercut ramp surfaces 54 enables the rear grip to be released essentially by a release movement of the second holding part 14 opposite to the direction of the arrow 50. When two forces are applied, the two contact surfaces 54 lead to a release movement with a small vertical component opposite to the direction of the arrow 50, which leads to the undercut of the undercut sections 28 and 42 being overcome. This results in a simple release for the customer of the secured goods from the holding connection with the first holding part 12 on the object, in that the customer only has a releasing force directed towards him or pointing away from the surface of the assigned object brings. The weight of the secured goods and the second holding part 14 counteracts the upward movement when the holding connection is loosened, so that unintentional loosening is prevented and unwanted damage to a goods fastened to the second holding part 14 is largely avoided.

2 shows the two holding parts 12 and 14 with the holding connection produced, the holding part 12 being fastened to a vertically running surface with vertically oriented longitudinal sides a and c. Accordingly, the second holding part 14 hangs with its head side b of the second connecting part 34 on the first connecting part 22 of the first holding part 12 at the top. The connecting cable 16 is in each case attached to the lower head sides d of the two holding parts 12 and 14 and hangs down in an approximately semicircular arc.

Corresponding to the described case of vertical attachment with vertical alignment of the longitudinal sides a and c of the device 10 according to the invention, it is also possible with the described exemplary embodiment to hold the holding part 12 on an essentially vertical or inclined upper surface. Y

surface of the object, not shown, to be fastened with horizontally aligned longitudinal sides a and c. This may be necessary, for example, if the object has a very flat housing, the vertical sides of which have a vertical extent which is substantially less than the longitudinal extent of the first holding part 12. In this case, a horizontal arrangement of the first holding part 12 on the object is recommended.

The fact that the undercut sections 28 and 42 are provided here on the sides a, b and c of the two connecting parts 22 and 34 which are at an angle to one another also results in a transverse alignment of the longitudinal sides a and c, with either one of the Longitudinal sides a, c can be arranged at the top, in the state attached to the object, a holding connection, as in the case described above, with a corresponding establishment and release of the connection. The only difference is that the undercut sections 28 and 42 come into engagement with each other in the region of the longitudinal side a or c lying on top. The same movement sequences and the same advantages result, that is, always a simple, secure holding connection that can also be easily solved again, as in the orientation described at the beginning.

It goes without saying that the holding part 12 can be attached to inclined or horizontally extending surfaces in addition to being attached to vertically extending surfaces of the object. In any case, a secure holding connection between the two holding parts can be established. /

With the exception of an overhead, horizontal alignment of the head side d of the holding part 12 facing the connecting cable 16, the illustrated embodiment 10 with its holding part 12 can be fastened to the object in any orientation and can thus be used and used universally. If necessary, however, the side b can also have the undercut sections 28, 42, for example, so that a secure holding connection between the holding parts 12 and 14 can be produced even when this side is positioned horizontally.

Due to the preferably rigid design of the connecting parts 22 and 34, the device 10 according to the invention has a long service life even when the device is used frequently. Furthermore, a relatively low release force is required precisely when the holding connection between the two holding parts 12 and 14 is released, so that the adhesive connections produced by means of the adhesive layer 20 between the first holding part 12 and the object and the second holding part 14 and the goods to be secured are little burdened and are therefore very durable.

3 and 4 show a second embodiment of a device 60 according to the invention for mechanically securing a product (not shown) against theft. The device 60 in turn comprises a first holding part 62 and a second holding part 64, which are connected by a flexible cable 66.

As in the first embodiment, the holding parts 62 and 64 each have essentially the shape of a flat cuboid, the first holding part 62 being used for a 16

is provided on an object and for this purpose has a fastening surface 68 with an adhered adhesive layer 70 on a flat side. The second holding part 64 likewise has a fastening surface 68 with an adhesive layer 70 on a flat side, which serves to fasten an article, not shown, to be secured.

Here, too, both adhesive layers 70 are formed by an adhesive tape that is adhesive on both sides.

The first holding part 62 has, on its flat side facing away from the fastening surface 68, a first connecting part 72 which is formed in one piece with the holding part 62.

The connecting part 72 is plate-shaped and has essentially the same flat cuboid shape as the first holding part 62. The first connecting part 72 has a recess 74 which essentially corresponds to the flat stump of a three-sided, irregular pyramid, the base of which faces the flat side of the first holding part 62. The recess 74 is arranged on the side edge of the connecting part 72, specifically on an end face 76 which lies opposite the fastening point of the cable 66 on the first holding part 62. The top surface of the truncated pyramid lies in the flat side of the first connecting part 72 facing away from the first holding part 62, so that the latter delimits the recess 74 by two undercut sections 78 which form run-up surfaces 79 which run in a V-shape with respect to one another and incline to the flat side.

The second holding part 64 has on its flat side opposite the fastening surface 68 an integral part with this Sem connected second connecting part 84, which is designed as a flat stump of an irregular, three-sided pyramid, which is connected at its top surface to the flat side of the second holding part 64. The second connecting part 84 is essentially complementary to the first connecting part 72, thus corresponds approximately to the shape of the recess 74. Furthermore, the second connecting part 84 on the second holding part 64 corresponds to the recess 74 on the first holding part Arranged 62, the protruding second connecting part 84 thus extends starting from an end face 86 of the second holding part 64, which lies opposite a fastening point of the cable 66 on the second holding part 64, with side surfaces tapering in a V-shape toward the center of the flat side of the second holding part 64. These side surfaces represent undercut sections 88 which form ramp surfaces 89 inclined to the flat side of the second holding part 64 and thus also to the fastening surface 68 thereof.

The holding parts 62 and 64 with their respective connecting parts 72 and 84 are injection molded in one piece from plastic, so that the device 60 can be easily manufactured.

Since both the connecting parts 72 and 84 and the holding parts 62 and 64 are rigid, there is no wear when using the device 60, and the service life of the device 60 is virtually unlimited.

The use of the device 60 according to the invention is described below. 2

In the exemplary embodiment, the first holding part 62 is glued by means of its adhesive layer 70 to an obliquely to the horizontal or to a vertical surface of an object for fastening the first holding part 62 to the object. Here, the first holding part 62 is aligned such that the recess 74 is at the top and the end face 76 of the first holding part 62 assigned to the recess 74 extends essentially horizontally.

The second holding part 64 is connected by means of its adhesive layer 70 to a product to be secured, not shown.

To produce the holding connection between the holding parts 62 and 64, the second holding part 64 is hooked with its second connecting part 84 into the recess 74 formed by the first connecting part 72. For this purpose, the second holding part 64 is moved with its second connecting part 84 ahead and approximately parallel to the first holding part 62 flat sides to the first connecting part 72 until the second connecting part 84 with its head surface 90 facing away from the second holding part 64 onto the first holding part 62 meets in the region of the recess 74. This relative movement between the two holding parts 62 and 64 takes place essentially perpendicular to the two fastening surfaces 18 of the holding parts 62 and 64 held approximately parallel to one another in the direction of the arrow 92.

The second holding part 64 then slides down with its second connecting part 84 on the first holding part 62 essentially parallel to the fastening surfaces 68 in the direction of the arrow 94, the tapered undercut sections 78, 88 acting as insertion bevels Second

and the establishment of a rear grip between them is easier. Thus, finally, the undercut sections 78 and 88 of the holding parts 62 and 64 come to rest against one another and an undercut between the two connecting parts 72 and 84 is produced over the entire longitudinal extent of the undercut sections 78 and 88. The resulting holding connection of the two holding parts 62 and 64 is very resilient, so that the goods arranged on the second holding part 64 are securely held by the object carrying the first holding part 62.

To release the holding connection, the second holding part 64 can be moved upward from the first holding part 62 in the opposite direction to the arrow 94 or, due to the inclination of the undercut sections 78 and 88, can be moved obliquely upwards in the direction of arrow 96 away from the first holding part 62. The run-up surfaces 79, 89 determine by their inclination with respect to the fastening surface 68 of the first holding part 62 and by their angular position relative to each other the inclination of the obliquely upward release movement 96, under which they can slide off one another when the holding connection is released.

The inevitable inclination of the release movement according to the invention with respect to a surface normal of the fastening surface 68 of the first holding part 62 leads to the fact that when the first holding part 62 is arranged as intended on a vertically extending surface of the object, the weight counteracts a loosening of the holding connection. In this way, an unintentional loosening and thus an undesired falling down of a product held by the second holding part 64 is prevented. In a preferred embodiment, the angle of inclination of the release movement in the direction of arrow 96 relative to the surface normal of the fastening surface 68 is 35 to 70 °.

The respective edge-side arrangement of the undercut sections 78 and 88 on the connecting parts 72 and 84 makes it possible for the suspension movement in the direction of the arrow 94 to deviate very greatly from the release movement in the direction of the arrow 96. However, the holding connection can be produced and released by a relative movement of the two holding parts 62 and 64 in relation to one another in a direction which lies in an angular range a, which is from the release movement in the direction of the arrow 96 on the one hand and against the insertion direction 94 ongoing movement is limited on the other hand. Accordingly, it is very simple to establish the holding connection, since no precisely defined insertion direction has to be observed, but rather the said angular range is available for the relative movement.

The inclined run-up surfaces 79, 89 enable the holding connection to be released by a releasing force acting perpendicularly to the fastening surface 68 of the first holding part 62 and acting on the second holding part 64. The inclination results in a force component running in the direction 96, which leads to a corresponding release movement of the second holding part 64 with respect to the first 62. Thus, the secured goods can be picked up by the customer by a force directed against the arrow 92, that is to say by a force directed away from the object, while the holding connection of the two holding parts 62, 64 is released. 2-2 »

Otherwise, the same advantages result in the second embodiment of the device 60 as in the first.

5 shows a third embodiment, which largely corresponds to the second embodiment described above, so that the same reference numerals are used as for the second embodiment and essentially only differences are shown below.

In the third embodiment of the device 60 according to the invention, the second connecting part 84 on the second holding part 64 is approximately plate-shaped, the plate plane running parallel to the fastening surface (not marked) and thus parallel to the flat sides of the cuboid-shaped second holding part 64, and with a first, rectangular section which adjoins the head side 86 and extends over the entire width of the flat side of the second holding part 64, and is provided with an approximately trapezoidal section which adjoins it. Here, the trapezoidal section adjoins the rectangular section with its side surface corresponding to the longer base side, and the side surfaces corresponding to the other sides of the trapezoid are designed as undercut sections 88, which form three run-up surfaces 89 inclined to the plate plane, so that two of these run towards each other and the intermediate third run-up surface 89 has an edge parallel to the head side 86.

The recess 74 of the first connecting part 72 on the first holding part 62 is formed corresponding to the trapezoidal section of the second connecting part 84, so that the first connecting part 72 passes through the recess 74 2..

delimits three undercut sections 78 which form run-up surfaces 79 running approximately trapezoidal and inclined to the flat side of the first holding part 62.

In the third embodiment, the narrow sides of the first holding part 62 adjoining the head side 76 are followed by widening sections 98, each of which are approximately cuboid in shape and projecting side surfaces on the flat side of the first connecting part 72 facing away from the first holding part 62 Make 100.

These side surfaces 100 run parallel to one another and are spaced apart from one another by a certain clearance over the width of the second holding part 64, that is to say the longitudinal extent of the head side 86, so that when the holding connection between the holding parts 62 and 64 is produced, the latter is included its longitudinal sides 102 adjoining the head side 86 can be inserted between the side surfaces 100. 5, the second holding part 64 must first be turned according to arrow 104 before the two connecting parts 72 and 84 are brought into engagement with one another, as already described for the second embodiment is.

The guidance imparted by the side surfaces 100 and the longitudinal sides 102 when the second holding part 64 is moved in and pushed into the first holding part 62 facilitates the production of the holding connection. In addition, this guide forms a very good securing of the second holding part 64 against rotation about an axis perpendicular to the flat sides of the holding parts 62, 64, ie around, when the holding connection is produced -2. 5

an axis perpendicular to the fastening surface 68 of the first holding part 62.

In a departure from the second embodiment, the device 60 according to the invention is designed in accordance with the third embodiment such that when the holding connection has been made, the holding part 64 in the area of its head side 86 and its opposite, unmarked head side protrudes laterally beyond the first holding part 62, the first holding part 62 with the lateral widening sections 98 projecting laterally beyond the second holding part 64 when the holding connection is made.

Otherwise, the device 60 according to the third embodiment according to FIG. 5 corresponds to the described second embodiment according to FIGS. 3 and 4, with a corresponding handling and use being provided and the same advantages being obtained. 5, the cable 66 connecting the two holding parts 62 and 64, of course, has been omitted for reasons of simplification.
