Abstract: A safety device prevents the terminal of an electrical plug from being disengaged from or engaged with an electrical receptacle. When the terminal is engaged with the receptacle, a tubular lock-in member slides over the plug to obstruct the release of a plug securing means that secures the plug to the receptacle. A retainer member attaches to the lock-in member and engages the receptacle or a part attached to the receptacle to limit the movement of the lock-in member. When the terminal is disengaged from the receptacle, a lock-out member obstructs contact between the terminal and the receptacle and engages the plug securing means. The lock-in member obscures the plug securing means and is secured to the lock-in member by the retainer member and the keyed lockable means.
