Abstract

A fastening element (10) for attaching a component to a support structure in a fastening direction (20), comprising a receptacle (30) receiving a tool nose (110) of a setting tool and having an abutment face (40) and a trap element (50), the abutment face (40) facing against the fastening direction (20) and abutting a front face (130) of the tool nose (110) when the tool nose (110) is received in the receptacle (30), the trap element (50) locking the tool nose (110) in the receptacle (30) in the fastening direction (20), and a slide-in channel (60) allowing sliding the tool nose (110) into the receptacle (30) and having one or more guide elements (70) guiding the tool nose (110) in a sliding direction (80) when the tool nose (110) is slid into the receptacle (30), wherein the sliding direction (80) is oblique to the fastening direction (20).

First claim

1 . A fastening element for attaching a component to a support structure in a fastening direction, comprising
a receptacle receiving a tool nose of a setting tool and having an abutment face and a trap element, the abutment face facing against the fastening direction and abutting a front face of the tool nose when the tool nose is received in the receptacle, the trap element locking the tool nose in the receptacle in the fastening direction, and a slide-in channel allowing sliding the tool nose into the receptacle and having one or more guide elements guiding the tool nose in a sliding direction when the tool nose is slid into the receptacle, wherein the sliding direction is oblique to the fastening direction.

2 . The fastening element according to claim 1 , wherein the sliding direction is perpendicular to the fastening direction.

3 . The fastening element according to claim 1 , wherein the trap element comprises a locking face facing in the fastening direction and engaging behind the tool nose when the tool nose is received in the receptacle.

4 . The fastening element according to claim 1 , further comprising a latch protruding in the slide-in channel and holding the tool nose in the sliding direction when the tool nose is received in the receptacle.

5 . The fastening element according to claim 4 , wherein the latch is spring biased into the slide-in channel and is pushed out of the slide-in channel by the tool nose when the tool nose is slid into the receptacle.

6 . The fastening element according to claim 4 , wherein the latch comprises a first chamfer on its side facing against the sliding direction.

7 . The fastening element according to claim 4 , wherein the latch comprises a second chamfer on its side facing in the sliding direction.

8 . The fastening element according to claim 4 , wherein the trap element comprises the latch.

9 . The fastening element according to claim 1 , wherein the trap element is spring biased against the tool nose when the tool nose is received in the receptacle.

10 . The fastening element according to claim 9 , wherein a spring force biasing the trap element against the tool nose corresponds to a minimum pull-out force to be provided to the fastening element against the support structure.

11 . The fastening element according to claim 2 , wherein the trap element comprises a locking face facing in the fastening direction and engaging behind the tool nose when the tool nose is received in the receptacle.

12 . The fastening element according to claim 2 , further comprising a latch protruding in the slide-in channel and holding the tool nose in the sliding direction when the tool nose is received in the receptacle.

13 . The fastening element according to claim 12 , wherein the latch is spring biased into the slide-in channel and is pushed out of the slide-in channel by the tool nose when the tool nose is slid into the receptacle.

14 . The fastening element according to claim 12 , wherein the latch comprises a first chamfer on its side facing against the sliding direction.

15 . The fastening element according to claim 12 , wherein the latch comprises a second chamfer on its side facing in the sliding direction.

16 . The fastening element according to claim 12 , wherein the trap element comprises the latch.

17 . The fastening element according to claim 2 , wherein the trap element is spring biased against the tool nose when the tool nose is received in the receptacle.

18 . The fastening element according to claim 17 , wherein a spring force biasing the trap element against the tool nose corresponds to a minimum pull-out force to be provided to the fastening element against the support structure.
