Joint socket and joint endoprosthesis

A joint endoprosthesis, in particular in the form of a hip joint endoprosthesis, comprising a joint socket and a shank, in particular in the form of a femur shank, which is coupled to the joint socket in a ball-jointed manner, wherein the joint socket is configured in the form of a joint socket having the form or substantially the form of a section of a hollow-spherical shell, wherein the joint socket comprises a socket wall, in which socket wall at least one through-opening is formed, which through-opening is closed with a closure element, which closure element is formed as one piece with the socket wall, wherein at least one predetermined breaking point is formed between the closure element and the socket wall, which at least one predetermined breaking point is irreversibly destroyable for removing the closure element from the socket wall, wherein the joint socket comprises at least one connecting device for at least one of force-fittingly and form-fittingly connecting the closure element removed from the socket wall to the socket wall in a connecting position.
