A device for handling or storing items uses jaw members that hinge to one of several closed positions in which the inner surface of a first jaw is engaged by an engagement device of the second jaw. An external release member in the second jaw is used to move the engagement device between an engaging and a disengaged position. The second jaw also incorporates a retaining surface, positioned opposite the outer surface of the first jaw when the jaws are closed, which opposes outward flexing of said first jaw member, and thus reduces the opportunity for disengagement due to forces from inside the jaws.
