Abstract
Disclosed is a hip joint socket for insertion into bone tissue, having an outer metal shell and an inner antifriction liner.

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..
