US Patent 6997734 Electric plug retention device

A device for holding the plugs of power tool cords and extension cords in electric contact having a C-shaped collar on each end of a rigid rod. Attached to each collar is a flexible band with complementary strip of separable adhesive material. When power tool cords and extension cords are plugged together and when the cords are placed in the collars, the collars abut the plugs. Wrapping the bands around their respective collars and pressing the adhesive strips together secures the cords in the collars. If a cord is jerked, the plugs will not lose electric contact, rather, the plugs will remain in contact and will move as a unit with this retention device.
