A ganged electrical receptacle unit with locking feature includes a plurality of receptacles and a lock housing. The electrical receptacles are ganged together. The lock housing extends from a front of the receptacles and includes a pair of opposed side supports, a pair of torsion bars, each extending between the opposed side supports, a lock tab extending from each torsion bar toward the receptacle, and a release tab extending from each torsion bar away from the receptacle. A plug may be inserted into the lock housing causing temporary deflection of the lock tabs until the plug is seated in, and electrically connected with, the receptacle, at which point the lock tabs return to their undeflected positions and retain the plug in the receptacle. The release tabs may be depressed to release the lock tabs from the plug, thereby permitting the withdrawal of the plug from the lock housing.
