The supporting members (2) comprise a sliding portion (3) having an opening (4) therein for passing the bar (1) and a supporting plate (5) extending from the sliding part (3), with a convex and concave surface (12, 13). Against the convex surface lies a ring (15) and against the concave surface lies a convex surface (21) of a receiving element (20, 27) in which screws (23) have been clamped, which can be secured in a bone part (24). Through the ring (15) extends a bolt (7) that has been screwed into one of a number of threaded bores (19) in the receiving element (20, 27) and which bolt extends through a relatively large opening in the supporting plate (5).
