Abstract: A quick-locking pin including a longitudinal rod, a first tightening stop at one end of the rod and a second tightening stop at the second end of the rod. The second tightening stop includes a second tightening ring, a lever mounted and journalled at the second end of the rod beyond the second tightening ring, the lever having a tightening cam off-centered with respect to its axis of rotation. The axle of the lever is borne by a cap located at the end of the rod between two arms. A transversely movable beam located between the arms of the cap is situated between the periphery of the cam and the external surface of the second tightening ring.
