The end implant parts (1, 2) form tubular sleeves (5', 5'') with sleeve walls perforated by openings (6) and interengage axially with their sleeves (5', 5''), whereby they are guided on the sleeve walls to be axially slidable with respect to each other, as well as secured against mutual pivoting about the sleeve axis. The thread (4) is provided between the center implant part (3) and the end implant part (1) connected therewith by the thread and the center implant part (3) pivotable in the thread (4) is designed as an axial stop for the other end implant part (2).
