<p>The invention relates to a fixing element for fixing a component to a support part. The element comprises a retaining part ( 1 ) for the component to be fixed and a hollow anchor foot ( 2 ), which is used to anchor the fixing element in a continuous bore of the support part. Two spring arm pairs ( 5, 6 ), which widen towards the retaining part ( 1 ), run from the lower edge in opposing openings ( 4 ) in the wall of the anchor foot ( 2 ), one short and one long spring arm ( 5 and 6 ) respectively lying adjacent to one another in one of the openings ( 4 ) and being offset in relation to the short and long spring arm ( 5 and 6 ) in the other opening ( 4 ). As both spring arm pairs ( 5, 6 ) are graduated towards the retaining part ( 1 ), starting from a respective outer edge ( 11, 12 ) that lies at the greatest radial distance from the central axis (M) of the fixing element, front faces ( 7, 8 ) and step faces ( 9, 10 ) are created on different horizontal planes. The faces can rest on the underside of a support part. Vertical bearing faces are created simultaneously ( 13, 14 ) at different radial distances from the central axis (M). The vertical faces can rest on the peripheral face of bores of varying diameters. The fixing element can thus be used both for a wide range of material strengths of the support part and for a wide range of diameters of the bore with high functional reliability. Both ranges can be covered by small graduation increments. An umbrella-shaped, spring stop ( 15 ) lying between the retaining part ( 1 ) and the anchor foot ( 2 ) permits a continuous adaptation between the stages for the range of material strengths.</p> |
