Abstract
A plastic ball socket extruded in one piece for a ball-and-socket joint having a shaft 5 and a ball end 8, the axis of the joint in standard position being lateral to shaft 5. The ball socket is divided by slot 13 extending into the area of its shaft 5. A cover-shaped locking part 4 to hold legs 11, 12 of ball socket 1 together is provided in the region of the open end of slot 13, consisting of two side sections 18, 19 and yoke part 20 connecting the two side sections 18 and 19 with each other. The one side section 18 has a projection 17 fitting over lip 16 arranged on the one leg 12 when locking part 4 holds the two legs 11, 12 together. The free end of the other side section 19 is connected with the other leg 11 via an elastic area forming a hinge strip 26. Within the region of the hinge strip 26, that side pointing away from slot 13 is provided with a recess 21 opening towards the outside, its edges 24, 25 leading outward and being a distance away from each other forming stops that limit the aperture angle of locking part 4, starting from that position in which locking part 4 holds the two leg end portions 14, 15 together.
