Abstract:
1. A clamping collar comprising a belt carrying first and second tightening lugs, a threaded tightening rod, first and second nuts that co-operate respectively with the first lug and with the second lug and are suitable for co-operating respectively by screw engagement with the tightening rod so as to bring the lugs towards each other in such a manner as to tighten the collar, the second nut being retained so that said second nut is prevented from moving in rotation relative to the second lug and in that the tightening rod has first and second threads of the same direction that co-operate respectively with the first nut and with the second nut in such a manner that driving the first nut in the screwing direction thereof successively causes said first nut to be screwed onto the first thread, the first nut to be stopped at the end of the first thread and the tightening rod to be driven, thereby screwing said tightening rod into the second nut.
