The present invention is a connector for connecting an electrical cable having cladding to an aperture in an electrical panel. The assembled connector has a spring, a shell, and a insulator along a longitudinal axis. The spring has a base from which two insertion tabs extend coaxial with the axis and two clad blocking tabs extending perpendicular from the two insertion tabs to prevent over-insertion of the cladding into the connector. The insertion tabs of the spring have hook latches extending past the insulator that lock the connector in the panel, and the base of the spring has a hole to receive the cable where clamping tabs clampably lock the cable in the connector.
