Joint endoprosthesis with an attachment part which can be attached and removed along a guide provided on the endoprosthesis, and with a screw (5) for locking the attachment part. This screw is arranged in the area of overlapping surface portions (7, 8) of the prosthesis and of the attachment part. A first surface portion (7) includes a threaded bore (13) receiving the screw (5). The screw shank has, adjacent to the screw head (10), a threaded section (12), adjacent to this a section (14) of reduced thickness, and adjacent to this a thickened end (15). The section (14) of reduced thickness lies in the area of the second surface portion (8), and namely in a slit (6) which extends in the direction of the guide and whose width is smaller than the thickness of the thickened end (15).
