Abstract

A clamping joint (10) is intended for connecting two construction elements (12, 14), in particular for an osteosynthetic fixator. It comprises a connecting element (15), two clamping elements (18) and two bracing means (16, 16') allocated thereto and beside each of which a transverse construction element which can be clamped between the connecting element (15) and the clamping element (18) is provided. Opposite thereto the clamping element (18) rests on the connecting element (15) in parallel with the bracing direction and it is thereby pressed against the connecting element with a bearing force acting perpendicularly to the bracing force, due to the moment generated by the bracing force, the bearing force bringing about a friction force between the clamping element (18) and the connecting element (15) which is the only one which reduces the bracing force on the construction element (12). For the two bracing means there are provided in each case a threaded screw (16) coaxial with the connecting element (15) and a nut (16') which comes to bear against the clamping element (18). This clamping connection (10) achieves a maximum clamping force on the construction elements (12) and, in addition, its elastic design effects bracing which is satisfactorily maintained even after a fairly long time. <IMAGE>
