Acetabular cup for a hip joint endoprosthesis consisting of a socket to be introduced into the hip bone, and an insert forming the joint surface. To secure the insert in the socket, a bayonet catch is provided with screw retention in the interacting edges of socket and insert. In the one edge an elongate depression is formed in the circumferential direction, into which depression there engages a screw head which projects from the other edge and which, with one end of the depression, forms a stop for finding the locking position. At this end of the elongate depression the latter comprises a bore into which the screw head can be screwed from the stop position, in order to secure the locking position.
