A fitting for securing an electrical cable to an electrically conductive junction box that provides improved electrical continuity between the fitting, the cable, and the junction box. The fitting features a hollow electrical connector having an electrically conductive split snap ring surrounding its leading end. The snap ring includes one or more grounding tangs cantilevered from its outer circumference and a locking tang lanced from each grounding tang. By providing locking tangs integral with the grounding tangs, a greater portion of the periphery of the snap ring is available for forming the grounding tang. The larger grounding tangs provide much greater surface contact between the grounding tangs and the junction box, thereby improving continuity and lowering the millivolt drop. Electrical continuity is further enhanced by the design of the grounding tangs, which extend from the snap ring at a rising slope to a crest and then at a downward slope to their free ends thereby enabling the downward slope portion of the grounding tangs to pull against the surrounding walls of the junction box and draw the fitting tight against the side of the box.
