Abstract
Disclosed is a collar which includes a belt carrying first and second tightening lugs, a threaded tightening rod, and first and second nuts that co-operate respectively with the lugs so as to bring them towards each other by screw engagement with the rod. The second nut is retained so that it is prevented from moving in rotation relative to the second lug and the rod has first and second threads that co-operate respectively with the first nut and with the second nut in such a manner that driving the first nut in its screwing direction successively causes said first nut to be screwed onto the first thread, and the tightening rod to be driven, thereby screwing said tightening rod into the second nut.
