A waterproof, swivel feature secondary plug and socket device suitable for use within a construction setting, for placement within an extension cord between an originating power source and a user end tool. The device allows a rotational movement between the plug and socket components such that cord twisting and buckling is eliminated, and strain on an operator is reduced. The device provides protection against cord damage or operator injury because, when too great a longitudinal traction force is applied along the cord, as when a cord becomes entrapped during use, the frictional fit between the plug and socket component allows an automatic separation of the unit with immediate withdrawal of electrical power from the cord. |
