Abstract: A bolt-on part, especially a front or rear bumper, of a motor vehicle, that can be exposed especially in its outer wall to impact energy and is mounted pointwise on a structural member of a motor vehicle, with the connection between the structural member and the bolt-on part consisting of pin-shaped fastening devices on one of the two parts to be connected and recesses in the other of the two parts, is intended to dissipate as much deformation energy as possible by coming loose from the structural member under the influence of an impact in the lengthwise direction of the bolt-on part. For this purpose, at least one of the recesses in each case is closed circumferentially and is located at the end furthest away in the direction of action from the point where the impact energy is applied. The other recesses are open circumferentially and are in the form of grooves inclined at less than .alpha.=90.degree.

Abstract: A fastening of a strip to a rearwardly accessible carrier part has arranged opposite one another on the longitudinal edges of the strip, pairs of holding tongues which are inserted through long holes arranged in the carrier part. At their free ends, the holding tongues are provided on the sides facing one another with respective hooks which themselves have a clamping face extending approximately parallel to the rear side of the carrier part. Arranged on the rear side of the carrier part for each pair of holding tongues is a double-winged rotary bolt which is pivotable about an axis of rotation perpendicular to the rear side and arranged between the respective mutually opposite pair of long holes. To lock the strip, the wings are pivoted inwards with their end regions between the rear side of the carrier part and the clamping faces of the hooks on the holding tongues, so as bear tautly against the clamping faces.

Abstract: A device is disclosed for holding a decorative cover on a bumper. Known holding devices provide either attachment of the decorative cover to the bumper in a manner fixed by means of a fastening clip or screw fastenings which are passed through an elongate hole in the bumper, the intention of this being that the elastic bumper should be movable relative to the decorative cover. The new device for holding a decorative cover includes a holding clip and a fixing pin, the decorative cover merely requiring to be pushed on rather than attaching by screw threads. The elongate hole is made in the holding clip. The pin is inserted with an accurate fit into the bumper and can be moved along the elongate hole relative to the holding clip and the decorative cover.
