<p>A fastening device for fastening an assembly in an opening of a wall of a vehicle is described. The fastening device has a supporting element (2) to be placed on the wall (1) and a retaining element (3) having at least one retaining wing (3.1) for fastening the fastening device in the opening (1.1) of the wall, wherein the retaining element (3) for fastening the fastening device is rotatably arranged relative to the supporting element (2), i.e., the retaining element (3) allows a quarter-turn fastener solution. In order to be able to mount without tools, at least one rotating wing (3.2) is arranged on the retaining element (3) and has a grasping surface (AF) in the direction of rotation for fastening the fastening device, said grasping surface being inclined at an angle (α) at least in the direction of rotation toward the direction of rotation and toward the wall. However, increased effort is usually required to remove inclined surfaces from injection molds. Therefore, the rotating wing (3.2) is preferably formed of a wall (3.2.1) that is approximately parallel to the axis of rotation and said wall (3.2.1) is reinforced by at least two webs (3.2.2) that are approximately perpendicular thereto but likewise parallel to the axis of rotation (A), wherein the webs (3.2.2) extend from the transition region (3.2.3) between the retaining element and the rotating wing across at least a part of the surface of the wall (3.2.1) of the rotating wing and are beveled toward the grasping surface (AF) such that on the whole a grasping surface (AF) is obtained that is inclined at least in the direction of rotation toward the direction of rotation and toward the wall.</p> |
