Abstract
A device for the attachment to a rod (1) of a member (24) such as a screw, a hook or the like, in particular for spinal instrumentation. The device interacts with a smooth rod (1) and comprises an intermediate socket in the shape of a split ring (22) engageable on said rod. A tightening means (23) is arranged on the ring (22) at the split therein so that when it is tightened, the rod (1) protrudes from the ring while engaging the bottom of a U-shaped body to which the member is secured, whereas the free ends of the ring flanges (221, 222) engage both the rod (1) and the body (21). The device is useful in the field of orthopaedic equipment fitted during spinal surgery.
