Abstract: An electrical connector is provided for joining the ends of two wires together or for joining an end of an electrical wire to a terminal lug. The connector employs a pair of electrically insulating jaws which diverge from an electrically insulating body. The jaws are resiliently biased apart and have mutually facing surfaces and opposite back surfaces. The back surfaces are configured with transverse serrations forming sawteeth that slope outwardly away from the body. Electrically conductive layers on the facing surfaces of the jaws define transverse clamping serrations. An annular clamping ring encircles the jaws and is longitudinally moveable therealong away from the body to force the jaws toward each other. The clamping ring thereby closes the jaws on the end of an electrical lead inserted between the jaws.
