The clamping wedges are composed of similar tapered segments joined together by link bars and pins to form an unending chain whose circumference is varied by a threaded drive screw joining the end segments. Decreasing the chain circumference forces the wedges onto mating tapers on the conduit joint, drawing them together by mechanical advantage. Structure is provided for permitting limited axial movement of the clamps during joint make-up to facilitate drawing together the parts to be joined from a separated position.
