    • The present invention describes an improvement to the standard 3-pin plug where the free end of a flexible cord can be coupled to it quickly without using a wire stripper. A plurality of leads 54, 56, 58 are disposed within the interior of the plug base 42. Each of the leads has an edge terminating in a plurality of saw tooth blades for perforating through the insulation of wires. The blades are exposed within a plurality of channels, while the other edge of the lead is embedded in the plug base. The channels are formed by a plurality of ridges disposed in the plug base 42. Preferably, the ridges are parallel to each other such that straight and narrow channels can be formed when the cover and the base are closed. In use, a person places the wires of the free end of a flexible cord within the channels in the base of present invention, closes the cover and the base, and connects the plug to a socket.
