Abstract

The invention relates to a multi-part clip for fastening an element to another element, the clip having at least a first component and a securing means.

Description

The invention relates to a multi-part clip according to the preamble of claim 1 and a multi-part clip according to the preamble of claim 2. These clips serve in particular to make it visually recognizable whether they have been securely attached or not.

Such clips are out US 2015/0300388 A1 known. A disadvantage of known clips is that the locking element contacts the locking pin in the intermediate position in the first position. The locking element and locking pin are coupled such that when the locking element is pressed into the second position, the locking pin is carried along so that it is moved out of an opening in the base body. As a result, the securing means is no longer secure in the intermediate position and can be displaced from this position in the event of impacts, for example. In the worst case, the securing means can fall out of the opening of the component.

Another disadvantage of known clips is that the securing means in the final assembly can slip unintentionally due to external forces. The relative position between the securing means and the component, which is a signal for whether the snap connection has been made securely by the clip or not, is changed thereby, which can lead to an incorrect assessment of the snap connection. Here, too, the securing means can fall out of the component in the worst case.

The object of the present invention is therefore to increase the reliability of generic clips.

The object is achieved according to the subject matter of claim 1 and claim 2. Advantageous embodiments are the subject of the dependent claims and the description that follows. Claim 1 and its subclaims relate to a first aspect of the invention.

The main idea underlying the invention according to claim 1 is that in the intermediate position the locking pin does not contact a locking element located in the first position. As a result, the securing pin is decoupled from the latching element in the first position in the intermediate position. This has the advantage that the locking element cannot move the locking pin when the locking element is moved from the first position to the second position. Thus, the contact between the nose of the locking pin and the edge of the opening in the base body can not be canceled by the locking element. In this case, the securing means therefore remains securely in the intermediate position regardless of the movement of the latching element. This circumstance is advantageous, for example, if the locking element is pressed in at a pre-assembly stage and at the same time the securing means remains in the intermediate position. Until the final assembly, in which the locking pin is in the end position, this ensures that the locking pin does not fall out of the component unintentionally. For example, one reason for falling out can be forces that act during transport of the preassembled product in such a way that they endeavor to move the locking pin out of the component. Another cause can be, for example, the weight of the locking pin, which is directed head down in the intermediate position.

Another advantage is that the clip according to claim 1 enables new assembly methods, in which the locking element is in a pre-assembly state in the second position, but the locking pin remains securely in the intermediate position until it is then brought into the end position in a subsequent assembly step , The absence of the interaction between the locking element and the locking pin located in the intermediate position therefore enables new applications in assembly, for. B. a staged assembly.

The at least first component is a fastening device. The first component has the task of attaching a first to a second element. The component has a head and a shaft with a tip. The shaft extends from the head along a shaft axis to the tip. The shaft has a base body and a locking element. The latching element has a contact surface pointing away from the tip. The head, however, also has a contact surface, but its contact surface faces the tip. The contact surfaces are thus facing each other. As a result, two elements that are to be attached to one another can be arranged between these contact surfaces. In particular, the elements are clamped between the contact surfaces in order to achieve a firm connection.

In order to achieve an attachment, the component is inserted with the tip into recesses which are made in the elements. The locking element passes the edge of the recesses and thereby moves from the first position to the second. This movement is possible because the locking element is usually designed to be resilient. If the locking element has been guided past the elements as the insertion progresses and is therefore no longer in contact with the edge of the recesses, the locking element springs back into the first position. The elements are then between the contact surface of the head and the Contact surface of the locking element, which ensures that the attachment is secure.

Secure attachment only takes place if the locking element springs back into the first position after being inserted. If this springback does not take place, the elements are not clamped between the contact surfaces and there is no secure attachment. To avoid this, a safety device is used. The relative position between the securing means that is inserted into the component and the component is a signal that indicates whether attachment has been carried out safely or not. If the relative position signals that attachment has not been carried out securely, corrective measures can in particular be taken by the assembly staff, for B. a stronger pressing of the component into the recess of the elements.

The force exerted by the contact surfaces on the elements in order to secure them to one another (clamping force) depends, among other things, on the thickness of the sections of the elements and, if appropriate, the thickness of further components (e.g. washers) which are between the Contact areas should be arranged (package thickness). The distance between the contact surfaces is usually constant or essentially constant. However, compensation elements can be used so that the first component can always exert sufficient clamping force with varying packing thicknesses. Compensating elements are in particular spring elements that can compensate for differences in thickness on the one hand and can increase the clamping force on the other.

The base body of the shaft has a test area. There is no section of the locking element in the test area when the locking element is in the first position. If, on the other hand, the latching element is in the second position, a section of the latching element is located in the test area. The section of the latching element that is located in the test area also has the function of preventing the inner part from being displaced into the end position of the base body.

The locking pin of the inner part has a section that extends into the test area when the inner part is pushed into the end position. However, if the section of the locking element is located in the test area, it comes into contact with the mentioned section of the safety pin when attempting to push the locking pin into the test area and thereby prevents further insertion of the inner part into the base body. In particular, the outer part of the securing means is thus at a greater distance from the head of the component than in the case in which the latching connection has been made securely (if the inner part of the securing means can thus be pushed into the base body into the end position). Because of this, it is clearly recognizable whether a secure snap-in connection has been made or not.

“Not contacted” in the sense of the invention means that in the intermediate position the locking pin does not touch or at least only touches a locking element in the first position in such a way that the locking pin does not change its position because the locking element changes from the first in the second position is moved. The locking pin preferably does not contact the locking element in the intermediate position even when the locking element is in the second position. Particularly preferably, the locking pin in the intermediate position does not contact the locking element even when the locking element is moved from the first position to the second position.

In a preferred embodiment, the locking pin is resilient and the nose can be pressed into the interior of the base body against an increasing restoring force from the position in which the nose is in contact with the edge of the opening.

In the sense of the invention, a “nose” is understood to mean a part of the securing pin which, in an intermediate position, passes through an opening in the base body of the shaft and comes to rest with an edge of the opening, so that further insertion of the securing means beyond the intermediate position is prevented wherein the nose can be pressed so far in the direction of the interior of the base body until the securing means can be inserted further beyond the intermediate position.

The wording that the nose extends through the opening is to be understood to mean that at least part of the nose is in the opening, and in particular this embodiment also includes the embodiment in which at least part of the nose also passes out of the base body through the The opening protrudes outwards (protruding part of the nose). This formulation also includes embodiments in which the nose touches the edge of the opening (as is the case in the intermediate position), but also embodiments in which the nose does not touch the edge of the opening.

The protruding part of the nose preferably serves to act on a force which is intended to press the nose in the direction of the interior of the base body. The process of pressing the nose in the direction of the interior of the base body is referred to here as a reset. Accordingly, the force that causes this reset is called the reset force. The amount of Restoring force is particularly dependent on the force application point, the shape of the protruding part and the way in which the nose and locking pin are connected. The restoring force can vary in size during the resetting, for example increasing or decreasing. This can e.g. B. be the case when the point of attack moves during the reset, z. B. because the edge of an element moves along the protruding part of the nose when the clip is inserted. The cause of the restoring force can therefore be a contact between the protruding part of the nose and an element. It is also conceivable that the restoring force is generated by the action of a tool on the protruding part of the nose.

In particular, the protruding part of the nose is designed in such a way that a restoring force that runs parallel to the direction of insertion but opposite it and acts on the protruding part of the nose causes the restoration. In order to be able to achieve this, the protruding part comprises an outer contour that is sometimes not parallel to the direction of insertion (bevel), e.g. B. an outside or outside edge. The bevel advantageously has an angle of essentially 45 °, 60 °, 65 ° or 75 ° to the direction of insertion, the part of the bevel which is closest to the opening being closer to the tip than the part of the bevel which is to the opening most distant.

This preferred function and nature of the protruding part of the nose enables the nose to be pressed from the edge of the opening of the element towards the inside of the base body when the clip is inserted into the opening of an element. The reset carried out in this way preferably does not result in the nose being pressed completely into the interior of the base body.

The nose extends from the locking pin at an angle to the direction of insertion. This angle is preferably essentially 90 °. The nose is advantageously attached to a surface of the locking pin that is essentially parallel to the direction of insertion. The lug is preferably attached to the end of the inner part that faces away from the outer part, so that the lug is the first part of the securing pin that penetrates into the component when the inner part is inserted into the component.

The reset function is ensured by the fact that the locking pin is spring-loaded.

According to the invention, the nose extends through an opening in the base body of the shaft in the intermediate position and comes to rest with an edge of the opening, so that further insertion of the securing means beyond the intermediate position is prevented. This is achieved in particular in that the nose has a section which is in contact with the edge of the opening when no restoring force acts on the nose of the locking pin located in the intermediate position (blocking section). The blocking section preferably has a side which is intended to be in contact with the edge of the opening in the intermediate position and which is essentially perpendicular to the direction of insertion.

In particular, the nose in the intermediate position also prevents the securing means from being pulled out of the component. This is realized in particular in that when trying to pull the securing means out of the component the nose strikes the edge of the opening. Pushing the securing means against the direction of insertion is preferably only possible when the nose has been pressed completely into the base body. The nose is completely pressed into the base body when it no longer reaches through the opening.

The nose can be pressed so far in the direction of the interior of the base body until the securing means can be inserted further beyond the intermediate position. In particular, this is realized in that the blocking section of the nose no longer comes into contact with the edge of the opening, but rather a section of the nose which enables the securing means to be inserted further, such as, for. B. the bevel of the protruding part of the nose. For example, if the securing means is pushed in further, the bevel can slide along an edge of the opening until the nose has completely penetrated the base body.

In a preferred embodiment, the inner part has a second securing pin, which has a section which, when the inner part is pushed into the end position, extends into the test area, and the second securing pin has a nose which extends at an angle to the direction of insertion and which, in the intermediate position, has a nose passes through the second opening in the base body of the shaft and comes to rest with an edge of the second opening, so that further insertion of the securing means beyond the intermediate position is prevented until the contact between the nose and the edge of the second opening is lifted, the intermediate position of the second locking pin does not contact a locking element located in the first position.

The second locking pin is preferably of the same type as the first locking pin. In particular, they have the same size and shape and are made of the same material. It is alternatively conceivable that the first locking pin is of one type and the second locking pin of another type.

The first securing pin and the second securing pin are preferably arranged opposite one another with respect to a plane which has the longitudinal axis of the inner part, in particular arranged opposite one another in mirror image.

In a preferred embodiment, the shaft has a second locking element. The second latching element has a contact surface pointing away from the tip and is movable between a first position and a second position. In the first position, part of the second latching element protrudes from the base body of the shaft. In the second position, the second latching element either protrudes less than in the first position from the base body or does not protrude from the base body at all.

The latching element can be moved between a first and a second position. In the first position, part of the latching element protrudes from the base body of the shaft. This part has the contact surface that points away from the tip. As a result, this contact surface can interact with the contact surface of the head, which faces the tip, in such a way that elements can be clamped between these contact surfaces.

In the second position, the latching element either protrudes less than in the first position from the base body or does not protrude from the base body at all.

The latching element is preferably designed to be resilient. The latching element is particularly preferably in the unloaded state in the first position and can be moved into the second position under the action of force, the latching element moving back into the first position when the force is removed.

The contact surface preferably consists of several, in particular two, sub-surfaces. The partial areas are preferably spatially separated from one another. The partial areas are preferably linked to one another in such a way that they move synchronously with one another.

The second locking element is preferably of the same type as the first locking element. In particular, they have the same size and shape and are made of the same material. It is alternatively conceivable that the first locking element is of one type and the second locking element is of another type.

In a preferred embodiment, the outer part of the securing means has a flat visible surface. A wing is connected via a hinge to the part of the outer part on which the flat visible surface is implemented. The wing can be pivoted between a position angled more towards the visible surface and a position less angled towards the visible surface.

The position of the wing serves as a signal that indicates whether the clip has been securely attached or not. The wing is preferably pivoted from a position that is more angled to the visible surface to a position that is less angled to the visible surface if the wing is pressed continuously against the head by progressively inserting the securing means into the component.

The term “hinge” in the sense of the invention is to be understood as a means which connects two parts to one another in such a way that the parts can be rotated in relation to one another about the longitudinal axis of this means. This term also includes a hinge as it is generally defined (e.g. a hinge for connecting the door and frame). According to the inventive understanding of the term “hinge”, however, any means that fulfills the function of a hinge defined in general terms is to be understood as a hinge. Accordingly, for example, a means that is flexible and elastic due to its shape or material can be understood as a hinge in the sense of the invention if it connects two parts in such a way that the parts can be rotated in relation to one another about the longitudinal axis of this means. The connection can have been made, for example, without connecting means such as screws, pins or adhesive if the means and the parts were preformed from one material (e.g. by injection molding).

Two wings are preferably attached to the visible surface. The wings are particularly preferably attached on two opposite sides of the visible surface.

“Less angled” in the sense of the invention also includes the case in which the angle between the wing and the visible surface is 0 °. In particular, in this case the wing lies in one plane with the visible surface. Due to the clear geometry, this arrangement of sash and visible surface is well suited for signaling that the clip is securely attached.

In particular, the wing is in a less angled position with respect to the visible surface when the inner part is pushed into the base body in the insertion direction up to the end position.

In a preferred embodiment, the first component is made of metal and / or the securing means is made of plastic.

The component is preferably made of metal. The component can alternatively be made of plastic. Embodiments are also conceivable in which a part of the component is made of metal and another part is made of plastic.

The securing means is preferably made of plastic. For example, it can be made by injection molding. The securing means can alternatively be made of metal. Embodiments are also conceivable in which part of the securing means is made of metal and another part is made of plastic.

The object is also achieved according to the subject matter of claim 2. Advantageous embodiments are the subject of the subclaims of claim 2. Claim 2 and its subclaims relate to the second aspect of the invention.

The main idea underlying the invention according to claim 2 is to secure the securing means, so that the inner part cannot be moved out of the opening of the head unintentionally. The relative position between the securing means and the component, which is defined by the insertion depth of the inner part in the component, is a signal for whether the clip has been securely attached or not. The unwanted movement of the inner part out of the opening of the head changes this relative position and harbors the risk of an incorrect assumption as to whether the fastening has been carried out safely or not. The invention according to claim 2 creates a multi-part clip according to the preamble of claim 2, which has increased reliability.

This is achieved by the invention in that the inner part has at least one resilient latching finger which can be moved from a protruding position into a less protruding position and springs back from the less protruding position in the direction of the protruding position when the force is removed. The locking finger has a locking surface that points against the direction of insertion. The securing means cannot be pulled out of the opening of the head when the locking finger is in the protruding position because the locking surface engages behind the edge of the opening.

The head of the component has an opening limited by an edge. The inner part of the securing means can be inserted through this opening in the direction of an insertion direction. The opening is preferably made on a surface of the head that faces away from the tip. The opening is preferably located in a plane perpendicular to the direction of insertion.

A force preferably acts on the latching finger in order to move the latching finger into a less protruding position when the latching finger is pressed continuously against the edge of the opening by progressively inserting the securing means into the component. The locking finger slides along the edge of the opening until a certain insertion depth is reached, at which the locking finger springs back.

In the context of the invention, “protruding position” is understood to mean a position of the latching finger in which it is more distant from the longitudinal axis of the inner part than in the less protruding position. The position of the locking finger in which it is furthest from the longitudinal axis of the inner part is the absolutely protruding position. In this position, no force acts on the locking finger, which tends to move it in the direction of the longitudinal axis of the inner part.

“Spring back” in the sense of the invention means that the latching finger moves from the less protruding position towards the protruding position. The locking finger does not necessarily have to move back to the absolutely protruding position (which is conceivable), but can also be moved to a second, less protruding position, the locking finger being further away from the longitudinal axis of the inner part in the second, less protruding position in the less protruding position. In this case, there is no loss of force, just a reduction in their amount.

For the purposes of the invention, the term “loss of force” includes the cases in which the force that acts on the locking finger to move it in the direction of the longitudinal axis of the inner part is eliminated and in which the amount of this force decreases. Which case applies to this term depends on whether the locking finger springs back into the absolutely protruding position or into a (relatively) protruding position.

The cause of the spring back can be, for example, the shape of the locking finger. The shape may, for example, have a recess at the end of the section which is intended to be pressed against the edge of the opening, so that after this section has passed the edge of the opening, this end reaches the edge of the opening, as a result of which the latching finger springs back ,

It is conceivable that the end of the latching finger has a section which protrudes from the opening of the head when the inner part is pushed into the end position, so that this section in FIG Direction of the longitudinal axis of the inner part can be pressed to release the securing means from the component again. This makes it possible, for example, to reuse the securing means.

The latching finger has a latching surface which points counter to the direction of insertion. The locking surface has the purpose of preventing the securing means from being pulled out of the opening of the head when the locking finger is springed back into the projecting position after the locking finger has been pushed into the opening.

The securing means cannot be pulled out of the opening of the head when the locking finger is in the protruding position because the locking surface engages behind the edge of the opening.

In a preferred embodiment, the latching surface engages behind the edge of the opening when the inner part has reached the end position. Since the inner part can preferably only be pushed into the end position when the snap connection has been made securely by the clip, the inner part can no longer move in the end position due to the fact that the latching surface engages behind the edge of the opening in accordance with this preferred embodiment , so that the relative position between the securing means and the component remains unchanged. Since the relative position between the securing means and the component is a signal for whether the latching connection has been made securely or not, this preferred embodiment provides a reliable signal, even if, for example, external forces strive to change this relative position during the assembly process.

In a preferred embodiment relating to the second aspect of the invention, the inner part has a further resilient latching finger which can be moved from a protruding position into a less protruding position and from the less protruding position when the force is removed in the direction of the protruding position springs back. The further locking finger has a locking surface that points against the direction of insertion. The securing means cannot be pulled out of the opening of the head when the locking finger is in the protruding position because the locking surface of the further locking finger engages behind the edge of the opening. The further locking finger is arranged opposite the first locking finger with respect to a plane which has the longitudinal axis of the inner part.

The further locking finger is preferably of the same type as the first locking finger. In particular, they have the same size and shape and are made of the same material. It is alternatively conceivable that the first locking finger is of one type and the further locking finger is of another type.

The further locking finger is arranged opposite the first locking finger with respect to a plane that has the direction of insertion. In particular, the first latching finger and the further latching finger are arranged opposite one another in a mirror-image manner with respect to this plane.

The use of a further locking finger according to this embodiment increases the reliability of the connection between the inner part and the base body. Unintentional loosening of this connection becomes less likely, especially if the inner part lies obliquely in the base body. In addition, a force that tends to pull the inner part out of the base body is distributed to several locking fingers, which reduces the load per locking finger.

In a preferred embodiment relating to the second aspect of the invention, the inner part can be pushed into the basic body in an insertion direction up to an end position, the inner part having a locking pin which has a section which extends into the test area when the inner part is pushed into the end position , and the locking pin has an nose extending at an angle to the direction of insertion, which in an intermediate position in which the inner part is partially inserted into the base body but has not yet reached the end position, passes through an opening in the base body of the shaft and with one Edge of the opening comes to rest so that further insertion of the securing means beyond the intermediate position is prevented until the nose can be pressed so far towards the interior of the base body until further insertion of the securing means beyond the intermediate position can take place , wobe i in the intermediate position of the locking pin does not contact a locking element located in the first position.

With this embodiment, the first and second aspects of the invention are realized. The advantages of both aspects of the invention thus come into play in one embodiment. In particular, the reliability of the clip according to the invention is increased.

The first locking element and the second locking element are preferably in relation to a plane which is the longitudinal axis of the base body has, arranged opposite, in particular arranged mirror-inverted opposite. The opening in the base body, which is penetrated by the nose of the first locking pin, and the opening in the base body, which is penetrated by the nose of the second locking pin, are preferably arranged opposite one another, in particular in mirror image, with respect to a plane which has the longitudinal axis of the base body arranged opposite. These two planes are particularly preferably essentially perpendicular to one another. The base body particularly preferably has four sides and the two latching elements are attached on two opposite sides, while the openings are attached on the other two, opposite sides. The openings are particularly preferably arranged closer to the head than the latching elements.

The invention also relates to a system with one element and another element and a clip according to the invention. The contact surface of the head rests on one element and the contact surface of the locking element rests on the other element.

Flat elements are particularly suitable as an element. This can be, for example, plates or sheets that are designed as part of a frame in a vehicle interior.

The invention is illustrated by the following drawings, which merely show exemplary embodiments of the invention. In it show:

1 shows an exemplary embodiment of a multi-part clip for attaching one element to another element, which encompasses both aspects of the invention. The clip has a first component 1 and a safeguard 2 on.

The first component 1 has a head 3 and a shaft extending from the head along a shaft axis 4 with a tip 5 on. The shaft 4 has a basic body 6 and two locking elements 7 on. The locking elements 7 each have one from the top 5 forward-looking contact surface 8th on. The contact area 8th consists of two partial areas in the present example 8a and 8b , The head 3 has one of the top 5 facing contact surface 9 on.

The locking elements 7 are movable between a first position and a second position, part of the locking elements 7 in the first position (as in 1 shown) from the basic body 6 of the shaft protrudes and the locking elements 7 in the second position (not shown) according to this exemplary embodiment, not at all from the base body 6 protrudes.

2 shows a sectional view of the clip. In the main body 6 of the shaft 4 is like 2 shows a test area 10 provided in which there is no section of a locking element 7 because the locking elements 7 are in the first position. Are the locking elements 7 fully depressed and thus in the second position, is in the test area 10 at least part of the locking elements 7 ,

The following is the 3 Referenced: The means of protection 2 has an outer part 11 on, which is intended to be outside the component 1 to remain (as per the 1 can be seen). It also has an inner part 12 on that in an insertion direction up to an end position in the base body 6 can be inserted. The inner part shows 12 two locking pins 13 on each one section 19 exhibit in the test area 10 is enough if the inner part 12 is pushed into the end position.

Every locking pin 13 also has a nose extending at an angle to the direction of insertion 14 on that in an intermediate position in which the inner part 12 partly in the basic body 6 is inserted, but has not yet reached the end position, an opening 15 in the basic body 6 of the shaft (see 1 ) and with an edge of the opening 15 comes to rest, so that a further insertion of the securing means 2 is prevented beyond the intermediate position. The 1 shows the belay device 2 in the intermediate position.

The following is a reference to 4 taken, which shows another sectional view of the clip in which the securing means 2 is in the intermediate position. The nose 14 can go so far towards the inside of the basic body 6 be pressed (see force A) until the safety device is pushed in again 2 can take place beyond the intermediate position (see force B). In the intermediate position, each locking pin contacts 13 a locking element located in the first position 7 Not. This is clear in 4 to recognize.

The head 3 of the component has an opening limited by an edge 16 onto. 5 ) through which the inner part 12 of the securing means 2 can be inserted in the direction of an insertion direction (as in the overview of 1 and 3 becomes clear).

Below is on 2 Referenced: the inner part 12 has two resilient locking fingers in the present example 17 that can be moved from a protruding position under the action of force into a less protruding position and spring back from the less protruding position in the direction of the protruding position when the force is removed. In 2 are the springy locking fingers 17 in the protruding position.

Every rest finger 17 has a locking surface 18 on, which points against the direction of insertion. The safeguard 2 can't get out of the opening 16 of the head 3 be pulled when the latch finger 17 is in the protruding position because of the resting area 18 the edge of the opening 16 reaches behind (see 8th ).

The following continues to refer to the 2 taken. The outer part 11 of the securing means 2 has a flat visible surface 20 on. In the present example there are two wings 21 over a hinge 22 with the part of the outer part 11 connected to which the flat visible surface 20 is executed. The wings 21 can between a stronger to the visible area 20 angled position and one less strongly to the visible surface 20 angled position can be pivoted. In 2 the more angled position is shown.

The position of the wings 21 serves as a signal that indicates whether the clip has been securely attached or not. The wings are here 21 from a stronger to the visible surface 20 angled position (see for example 2 ) in a less strong view area 20 angled position (see for example 8th ) pivots when the wing 21 by progressively inserting the securing device 2 into the component 1 persistent against the head 3 pressed and against the head for so long 3 slide until they are almost level with the visible surface 20 lie. This arrangement of wings 21 and visible area 20 Due to the simple geometry, it is well suited for signaling the secure attachment of the clip. This arrangement therefore arises when the inner part 12 was pushed into the end position, the locking elements 7 thus have moved back into the first position after insertion into recesses of the elements. Because only if the locking elements 7 are in the first position, it is possible the inner part 12 to the end position, because then the test area 10 (S. 2 ) for the section 19 (S. 3 ) free is.

In the following, reference is made to 6 : The force exerted by the contact surfaces 8a . 8b and 9 exerted on the elements in order to fasten them to one another (clamping force) depends, among other things, on the thickness of the sections of the elements and, if appropriate, the thickness of further components (e.g. washers) which are between the contact surfaces 8a . 8b and 9 (the contact area 9 [that of the head] is in 6 not visible) should be arranged (package thickness). In the present example, the distance between the contact areas is 8a . 8b and 9 essentially constant. However, this is the first component 1 with varying packing thicknesses can always exert sufficient clamping force, a spring element can act as a compensating element 23 be provided, which on the one hand compensates for differences in thickness and on the other hand increases the clamping force.

In the following, reference is made to 7 that made up the multi-part clip 1 shows. In contrast to 1 is in 7 the safeguard 2 not in the intermediate position, but in the end position. The nose 14 no longer reaches through the opening 15 in the basic body 6 , Instead, the nose is completely in the body. This is in 9 to see a sectional view of the multi-part clip 7 shows.
