The electrical receptacle has a main blade member or bus bar with a terminal end portion thereof forming a first jaw at the end of the receptacle. A jaw member overlies and is rigidly secured to the main blade member, with a terminal end portion thereof forming a second jaw at the end of the receptacle. The overlying main blade member and jaw member having cooperating relatively straight contact faces that face one another on opposite sides of a narrow insertion space for receiving said blade-like contact.
