A connector device and system for joining electrical conductors is presented. The connector device is comprised generally of an elongated body having at least two tapered ends. Each tapered end has male threads disposed on the exterior surface and at least one compression groove. A compression nut having an internal taper matching the angle of the taper of the tapered end is disposed on each tapered end. In use, a conductor is inserted into one tapered end and the compression nut is rotated towards the center of the elongated body thus compressing the compression grooves and providing enhanced mechanical stability and electrical conductivity by providing 360 degree contact of the connector device with the conductor.
