ABSTRACT:
A plug lock for receiving an engaged plug and connector. The plug lock comprises a first side and a second side. Each of the first side and the second side have ribbed interior walls. A first end abutment connects the first side and one end of the second side. The first end abutment has a cord opening. The second end abutment is positioned opposite the first end abutment and connects the first side and the second side. The second end abutment has a clamp opening and a clamp portion extending through the clamp opening. The clamp portion has an outer surface with diametrically opposed ribbed portions configured to engage the ribbed interior walls of the first side and the second side and diametrically opposed smooth portions to slide over these ribbed interior walls. In use, a female plug terminates an electrical cord led through the clamp portion. A male plug terminates an electrical cord led through the cord opening and the male plug is engaged in the female plug. The clamp portion is positioned with the diametrically opposed smooth portions facing the ribbed interior walls and moved longitudinally against the engaged plug so that the connector holds the engaged plug against the first end abutment. The clamp portion is then rotated so that the diametrically opposed ribbed portions engage the ribbed interior walls to lock the clamp portion in position.
