ABSTRACT:
Disclosed is a hip joint socket for insertion into bone tissue, having an outer metal shell and an inner antifriction liner. The antifriction liner is fixed in the metal shell by means of a taper lock. To safeguard the socket insert and antifriction liner against misalignment and separation, and enable a non-destructive removal of the liner and replacement thereof, the angle (.alpha.) of the taper lock of the liner in the shell is between 10.degree. and 25.degree..
