ABSTRACT:
A camlock for engaging the inside of tubular members thus suspending apparatus from the tubular members comprises a movable spacer disposed on a slidable member between two metal rings. The relative motion of the spacer and slidable member causes the metal rings to be expanded against the inside of the tubular member thereby supporting the apparatus. The metal rings have a thin wall with internal ribs that fit closely to the slidable member. The internal ribs act as stops on the inside of the metal rings so as to prevent their overexpansion.
