  • Patent number: 6120311
    Abstract: Apparatus for securing an electrical power cord against theft comprises cylindrical tube rigidly attached to a padlock. The cord passes through the tube's bore. The bore is too small to pass the enlarged cord ends or plugs, trapping the cord in the tube. The cord cannot be removed without first removing the cord ends or severing the cord. The padlock can be locked to any secure structure, rendering the cord resistant to theft.
