摘要

An optical assembly, especially for an automobile vehicle, is fixed and pivoted on a support by a screw threaded in the support and carrying a ball at its free end. The ball engages in a socket mounted in a housing fixed to the optical assembly. According to the invention, the socket is moulded from plastics material and comprises two parts connected by a live hinge disposed substantially in line with the center of the concave seating. After assembly the socket is fitted into a sleeve in the housing, which prevents opening of the hinge.
