A device for preventing the unauthorized removal of electrical appliances having a cord terminating in a plug with two prongs having aligned holes therethrough, comprises an enclosure adapted to be opened and closed and having holes through a side wall thereof of a size to permit the insertion of the prongs through the holes but to prevent insertion of the plug through the holes. The enclosure is locked against unauthorized opening. A spring clip within the enclosure is removably engageable within the holes through the prongs and releasably retains the prongs within the enclosure. The enclosure comprises two portions hingedly interconnected, and the lock releasably retains these two portions closed together. The enclosure comprises polygonal channels which, when closed together, form a polygonal enclosure of closed polygonal cross-sectional configuration, preferably rectangular, for example square.
A device for preventing the unauthorized removal of electrical appliances having a cord terminating in a plug with two prongs having aligned holes therethrough, comprising an enclosure comprising two portions hingedly interconnected and adapted to be opened and closed and having holes through a side wall thereof of a size to permit the insertion of said prongs through said holes but to prevent insertion of a said plug through said holes, a lock releasably retaining the enclosure closed against unauthorized opening, and means within the enclosure removably engageable with said holes through said prongs to releasably retain said prongs within said enclosure.
A device for preventing the unauthorized removal of electrical appliances each having a cord terminating in a plug with two prongs having aligned holes therethrough, comprising an elongated enclosure adapted to be opened and closed and having holes through a side wall thereof of a size to permit the insertion of said prongs through said holes but to prevent insertion of a said plug through said holes, said holes through said side wall of said elongated enclosure being disposed in spaced pairs lengthwise of one wall of said elongated enclosure, thereby to permit the insertion of the prongs of the plugs of a plurality of electrical appliances through each of a plurality of pairs of said side wall holes, thereby to permit the protection of a plurality of electrical appliances against unauthorized removal, means releasably to retain the enclosure closed against unauthorized opening, and means within the enclosure removably engageable within said aligned holes through said prongs to releasably retain said prongs within said enclosure.
