摘要：
The present invention relates to a joint socket (1) for a hip joint prosthesis, with a metal outer shell (2) and with a preferably ceramic inner shell (3). The outer shell (2) and the inner shell (3) are held together with a force fit by shrinkage and are connected to each other by at least one additional form-fit means (4； 5). The at least one form-fit means (4；5) is arranged on the periphery in the equatorial edge region of the joint socket in such a way that, as a result of the shrinkage stress, it forms a sealing operative connection between outer shell (2) and inner shell (3). The present invention further relates to a method for producing a joint socket (1), in which method a metal outer shell (2) is shrink-fitted onto a preferably ceramic inner shell (3), wherein at least one peripheral form-fit means (4；5) in the equatorial edge region of the outer shell (2) engages in a corresponding means of the inner shell (3).
