Fastening clip
View Patent ↗A fastening clip for fastening a component to a carrier, has a holding member, the holding member being adapted to be inserted into an opening of the carrier in an insertion direction and the holding member includes a plurality of expansion arms adapted to engage behind the opening of the carrier, and an expansion member adapted to be inserted into a recess of the holding member contrary to the insertion direction so that the expansion arms are transferred from an initial position to an expanded position, wherein the holding member and the expansion member are integrally connected with each other in a preassembly position by connecting webs which each constitute a predetermined breaking point and which are provided in particular between the front end of the holding member viewed in the insertion direction and the rear end of the expansion member viewed in the insertion direction.
1. A fastening clip for fastening a component to a carrier, comprising a holding member, the holding member being adapted to be inserted into an opening of the carrier in an insertion direction and the holding member includes a plurality of expansion arms adapted to engage behind the opening of the carrier, and comprising an expansion member adapted to be inserted into a recess of the holding member contrary to the insertion direction, so that the expansion arms are transferred from an initial position to an expanded position, wherein the holding member and the expansion member are integrally connected with each other in a preassembly position by connecting webs which each constitute a predetermined breaking point and which are provided in particular between a front end of the holding member viewed in the insertion direction and a rear end of the expansion member viewed in the insertion direction.
2. The fastening clip according to claim 1 , wherein corresponding detent members are provided on the holding member and on the expansion member for fixing the expansion member in place on the holding member in an intermediate assembly position, in which each predetermined breaking point has been broken and the expansion member partially inserted into the holding member, but the expansion arms are in the initial position.
3. The fastening clip according to claim 2 , wherein a detent connection is formed by a detent hook and an oblong recess in which the detent hook can be shifted in the insertion direction, so that the expansion member can be shifted from the intermediate assembly position to a final assembly position without releasing the detent connection.
4. The fastening clip according to claim 1 , wherein provided on the holding member is a pulling means, in particular a screw, which engages the expansion member and is adapted to pull the expansion member into the holding member contrary to the insertion direction.
5. The fastening clip according to claim 1 , wherein provided on an outside of the holding member are detent tongues which are adapted to engage in the opening of the carrier.
6. The fastening clip according to claim 5 , wherein a plurality of detent tongues is provided, each located opposite each other in pairs and spaced apart from each other in the insertion direction.
7. The fastening clip according to claim 1 , wherein the holding member is of a rectangular design and detent tongues are provided on opposite side surfaces.
8. The fastening clip according to claim 7 , wherein the expansion arms are provided on two remaining surfaces of the holding member.
9. The fastening clip according to claim 1 , characterized in that the expansion member has insertion slopes which press the expansion arms radially outwards.
