The invention relates to a device for testing a ceramic socket insert (3) for hip joint implants having a receiving device (5), a pressure piece (6) and optionally having a plunger (7), wherein the receiving device (5) has a recess (9) with a positioning region (10) for receiving the socket insert (3) and the recess (9) has a receiving cone (11) in the positioning region (10). According to the invention, in order for the device to be universally applicable to all socket inserts (monolithic, modular, pre-joined) and therefore replace all current devices, an annular ductile adapter piece (8) having a conical outer surface contacting the receiving cone (11) and an inner surface contacting the socket insert is arranged in the positioning region (10) between the receiving device (5) and the socket insert (3), wherein the friction between the receiving device (5) and adapter piece (8) is lower than between the adapter piece (8) and socket insert (3).
