Abstract: An electrical cord to plug tension relief adapter and wire saver/protector is provided. The invention consists of a housing containing a cam mechanism, and a universal plug seating head that is assembled and attached securely over any selected electrical cord/plug outfit at the plug end, so as to surround, bridge, and protect the joined point of connection where the plug meets the cord. A multiple pivoting cam mechanism within the housing creates an S-Shaped slotting pattern which is configured to enable the internal threading of various sizes and styles of electrical cords. The multiple cam mechanism engages and securely grips the cord when it is pulled on, and thereby creates a strengthened anchoring position where the tension force is redirected. The universal seating head is designed to encircle, accept, seat, and partially secure the selected plug end, by means of it's distinctive shape.
