In a known headlight for a motor vehicle, a lens is glued to a headlight shell. According to the invention, a cover disk is surrounded, on its outer circumference, with at least one outwardly projecting profile shoulder. A sealing profile is designed as a securing frame which form-lockingly reaches over the profile shoulder of the cover disk and is mechanically fastened to the shell. The fastening arrangement is used for front headlights of passenger cars.
