US Patent 7553181 Cord connection device

A cord connection device that is used to secure the connection between two existing extension cords or between a power tool and an extension cord. The device has an outer casing that is split in two parts which are pivotally attached to one another along their length, with the outer casing being tapered inward toward each of its ends to allow a better fit around the body of each of the cords. The plugs of the cords are connected to one another within the outer casing and have an intervening contact plate located in between them. The contact plate is connected via a wire to a light emitting diode (LED) that is located on the exterior of the outer casing, with the LED lighting up when current is passing through the connected cords.
