Abstract
Detachable device for joining together objects having holes intended to come into alignment, comprising: PA1 a tubular member made of an elastically deformable material and capable of passing through the holes when it is in the expanded state and of widening in order to be locked in the holes, PA1 an expansion rod sliding inside the tubular member and having a widened head, PA1 a body fastened to the tubular member and having a bore which extends the bore of the tubular member, and a support surface substantially at right angles to said bore, PA1 a locking member which can be immobilized at any point on the rod, PA1 an elastic member capable of exerting a determined force tending to move the body away from the locking member. The tubular member, the body and the elastic member preferably form a single piece.
