?TRACT A security attachment for an electrical plug is effective to prevent unauthorized use but to readily permit authorized use. It comprises a pair of adapter elements which are mutually plugged to- gether between the electrical plug and a wall receptacle. One adapter is plugged together with the electrical plug and the two are connected together such that they cannot become unplugged if an attempt is made to unplug them. When unauthorized use is to be prevented, the other adapter is removed to expose prongs of the first adapter which pre- vent the first adapter from being plugged into the wall receptacle.
