Abstract: An electrical cord plug lock assembly having a special electrical socket face plate with a pair of laterally spaced locking brackets extending outwardly from its front surface adjacent the opposite sides of the socket aperture. A base clamp member has a locking arm pivotally secured to its respective left and right ends. The front end of the locking arms have structure for detachably securing them to the respective locking brackets on the front of the electrical socket face plate. A top clamp member is detachably secured to the top surface of the base clamp member and it functions to grip an electrical cord there-between. The electrical plug lock assembly prevents accidental removal of the electrical plug from the electrical socket.
