Abstract

A lock for joining cables, chains and the like comprising identical parts attached to the cable ends. Each part comprises a hollow cylinder in which is positioned a lever extending lengthwise of the cylinder and attached for limited pivoting action. Each lever end forms a lip which overlaps and interlocks with the lip of the other lever end when the cylinders are butted end-to-end. For disengaging the cylinder ends these levers are pivoted to a nonoverlapping position and the cylinders are pulled apart.
