Classification: CPC B  F | IPC B  F

Claim 7:
8. Apparatus for fastening a component to a carrier component, comprising:
a base body, wherein the base body comprises first catching means for fastening the apparatus to a carrier component, and
an actuating element via which the apparatus can be subjected to a force acting in an assembly direction in order to transfer the apparatus from a pre-assembly position into a final assembly position, wherein the assembly direction extends orthogonally to a surface of a carrier component, and
wherein the actuating element comprises at least one catching element, which, in the pre-assembly position, engages with a correspondingly formed pre-assembly catching element of the base body and, in the final assembly position, engages with an assembly catching element of the base body, wherein a connection of the catching element to the assembly catching element verifies that the final assembly position is reached, such that the actuating element forms a visual assembly verification device;
wherein a plurality of spring elements are arranged approximately equally spaced apart from one another on the base body radially circumferentially, which extend approximately radially orthogonally to the assembly direction in such a way that the apparatus and a component fastened to the apparatus in the final assembly position can be subjected to a spring force acting counter to the assembly direction, wherein a retaining force between the catching element of the actuating element and the pre-assembly catching element of the base body in the pre-assembly position is greater than the total spring force of all spring elements, such that the actuating element is only transferable into the final assembly position and its catching element is only engageable with the assembly catching element of the base body when the spring elements are biased in such a way that the apparatus can be subjected to a predetermined spring force acting counter to the assembly direction.
