Abstract
A reinforced fastening point for a plastics-material casing. In order to provide a reinforcement for a fastening point which is simple to assemble and which is held automatically in the opening in the casing without further fasteners, a cylindrical opening is provided at the fastening point on the casing. The reinforcement part corresponding thereto is constructed as a frustum in that region which in the assembled state comes to rest in the region of the cylindrical opening. The smaller external diameter of this frustum is smaller than or equal to the internal diameter of the cylindrical opening. The larger external diameter of the frustum, on the other hand, has an excess dimension with respect to the internal diameter of the cylindrical opening. In this case, the excess dimension is selected to be such that it can be neutralized by resilient deformation of the reinforcement part.
