摘要： The present invention relates to a device that prevents unauthorized use of an appliance inasmuch as the unauthorized use results in clear evidence of such. Basically the device of the present invention comprises an electrical coupler having means for receiving a male appliance plug and male plug means for insertion into a conventional electrical outlet. A flexible tie device is provided that binds and effectively locks the male appliance plug to the electrical coupler in such a manner that the male appliance plug cannot be removed from the electrical coupler without destroying the integrity of the flexible tie device. In addition, a lock type switch is operatively associated with said electrical coupler for opening and closing the electrical circuit therein and as such, the same provides a master control for a coupled appliance.
