A device for temporarily coupling together and subsequently separating a first member and a second member, comprises:
a male member joined to the first member;
a female member joined to the second member and comprising an axially elongate hollow body in which are disposed a retaining sleeve adapted to retract radially onto the male member or to expand, a piston sliding axially to retract/expand the retaining sleeve and, in the piston, disposed along the axis, an ejector finger joined to the piston by a readily broken member, and
selective control means for the piston adapted to command movement of the piston and optionally simultaneous breaking of the readily broken member and to cause the ejector finger to slide axially, the finger projecting axially relative to the piston.
