Fixing element for securing a retaining element on a support and system comprising a fixing element and a retaining element

1. A fastener for securing a retaining element on a support, wherein the fastener is formed like a retaining clip and has at least one leg and at least one engaging section, wherein the engaging section extends outwardly from the longitudinal axis of the fastener and is capable of engaging the retaining element, wherein the leg has at least one latching section for retaining the retaining element on the support, wherein the fastener has a channel for receiving a section of the retaining element, wherein the fastener has at least one contact region for contact with the retaining element that is positioned at least partially within the channel, wherein the contact region is connected to the engaging section via a connecting section, wherein the contact region extends at an angle greater than 0° and less than 90° to the longitudinal axis of the channel, wherein the fastener has at least one outwardly extending further engaging section that adjoins the contact region, and wherein the further engaging section is connected to the contact region via a further connecting section extending through a window defined by the leg of the fastener.

2. The fastener according to claim 1 , wherein the engaging section encloses an angle of less than or equal to 90° with the longitudinal axis of the fastener.

3. The fastener according to claim 1 , wherein the contact region has a deflecting section, or a deflecting section adjoins the contact region, wherein the deflecting section is arranged in the region of the channel.

4. The fastener according to claim 3 , wherein the contact region forms, with the connecting section and the deflecting section in the direction of the longitudinal axis of the fastener, a part of a V-shaped, U-shaped, diamond-shaped, partially circular or partially elliptical section.

5. The fastener according to claim 1 , wherein the window is defined in a section of a leg which has an angle not equal to 0° to the longitudinal axis of the fastener.

6. The fastener according to claim 1 , wherein the distance of the engaging section from a central axis of the fastener is greater than the distance of the further engaging section from the central axis of the fastener.

7. The fastener according to claim 1 , wherein the fastener has a groove-shaped recess, or bead, or detent lug extending into the channel.

8. A system comprising a fastener according to claim 1 and a retaining element, wherein a distance between the engaging section and the contact region in the longitudinal direction of the fastener is adapted to a distance between a contact surface of the retaining element against which the engaging section can rest, and a latching element which is provided on a section of the retaining element to be received by the channel and against which the contact region rests.

9. The system according to claim 8 , wherein the section of the retaining element located in the channel is adapted to the fastener in such a way that both a contact of the section on the contact region and on a region of the leg facing the contact region in the section of the fastener is made possible.

10. The system according to claim 8 , wherein the latching section is formed by a latching ramp which extends at an angle to the longitudinal axis, and is located on the other side of the contact region in comparison with the engaging section and has a surface facing the surface of the engaging section coming into contact with the contact surface of the retaining element.

11. The system according to claim 10 , further comprising a catch section having a surface which faces the surface of the engaging section coming into contact with the contact surface of the retaining element, wherein the catch section is arranged farther along the longitudinal axis from the engaging section in comparison to the latching section.
