Abstract
A system for attaching a wire shield and a cover cap to the rear of an electrical plug. The plug is provided with four U-shaped members extending outwardly from the periphery of the plug casing, two on each of the opposite sides of the casing, near its corners. Four latching prongs extend forwardly from the shield, in alignment with the U-shaped members, each of which when advanced into a U-shaped member engages a detent shoulder on the inside of the top of the U-shaped member, to accomplish the desired latching. The cap, if used, has four forwardly-extending latching prongs each positioned to slide into a U-shaped member, just below the shield-latching prongs, until it engages a detent shoulder on the casing below the shield prong. Support structure integral with the U-shaped member preferably provides support to hold the shield latches in place even if the cap prongs are not present, as when a cap is not used.
