An electrical connector and dual purposes test jack used for testing electrical devices includes both a spring clamp member and a "plug in" pin assembly. The pin assembly has, at one end, an electrically conductive wire receiving portion, a setscrew for attaching an electrical wire thereto, an insulator sleeve therearound and, at the opposite end, a cylindrical, radially compressible, bifurcated, conductive pin having an externally threaded inner end portion. The spring clamp member has, at one end, an electrically conductive tubular receptacle internally threaded adjacent the end thereof and, and its other end, a conductive spring clamp. The pin is longitudinally bifurcated at its outer end portion and is dimensioned such that it may be axially inserted past the internal threads of the receptacle and securely held therein place by the radial compression thereof. For a more secure connection, after axial insertion into the receptacle, the pin may also be screw-fitted within the receptacle by rotating a small number of turns.
