Abstract

A clamp for the pins and rods of a bone fixator made of a lightweight plastics material and comprising a pair of clamping discs (1, 2) mounted on a common axis. The pins and rods are held in a passageway (17) or passageways formed between the confronting faces (4, 10) of the discs. To resist separation and relative rotation of the discs (1, 2) as the discs (1, 2) are pulled together by an axially mounted clamping bolt, the confronting faces (4, 10) are provided with specially designed interengageable formations comprising a recess (8) across one face and a complementary projection (14) across the other face.
