Claim:
An improvement to clips for fastening accessories to vehicle panels formed by stamping a plate made of metal to form an approximately rectangular base, from which there extends on opposite sides a resilient securing structure in the form of flexible fins, said improvement comprising a descending upper fin which is extended in an inverse direction in order to form a second ascending lower fin having in an area immediately adjacent to said base a rectangular reinforcement case which is formed by an end contact of opposite mid parts, there being provided, starting on said opposite sides of said base, in each case flexure arms which act resiliently on a panel, wherein the said rectangular reinforcement case is formed by means of a fitted-together join of a single finger per side of each mid part, formed by means of a shape approximately of a double fold in the form of a zig-zag against an edge of the opposite mid part, which extends in parallel to walls of the rectangular reinforcement case and in the interior of the rectangular reinforcement case, wherein the fingers form a symmetrical interlacing at the mid parts; and wherein the flexure arms have a fold which permits extension of said flexure arms inwardly in a direction which converges toward the clip.
