ABSTRACT:
A portable security device comprised of a sturdy, lockable enclosure housing a standard electrical outlet. The electrical outlet is secured within the enclosure, and the power supply to the outlet is capable of being interrupted by the action of a keylock switch from the exterior of the enclosure. The wall of the enclosure opposite the outlet is provided with one or more slots, aligned with one or more plug outlets. The enclosure includes a hinged cover, which may be unlocked and raised to allow standard electrical cords for external appliances or devices to be lowered into the slots, while the respective plugs are inserted into the aligned plug outlets. Each of the slots formed in the wall of the enclosure is only wide enough to accommodate the width of an ordinary electrical cord to thereby prevent the passage of the plug of the cord through the slot. When the cover of the enclosure is in the lowered position and locked in place, the cover insures retention of the plugs in their respective outlets.
