Abstract: A novel electrical plug comprising two identical members longitudinally combined face-to-face with each other, each member at an inner side comprising four sections including, in sequential order from rear to front end, a support section defining a groove for accommodating a connecting wire, a terminal receiving section having a recessed platform and a central polygonal hole to receive a terminal screw, a fulcrum section forming a pair of semi-circular protrusions spaced apart from each other and a pair of semi-circular recesses at the remainder spaces, and a spring retention section having a platform at a level lower than that of the platform at said terminal receiving section and a central through hole to retain a coil spring which has hooks at both ends extending and fastening at the outer side of both members and thereby combining said members together, and at the front end comprising a conductor integrally formed therein.
