Abstract: A tool for disconnecting the air and electrical connections between a motor vehicle and a trailer or a utility hookup station includes a handle and a forked member. The trailer connection includes an electrical socket with pins covered by a hinged cover plate; the motor vehicle connection includes a plug member. The forked member of the tool includes a pair of parallel hooks, one at the end of each of two linear elements of the forked member. A sloped interface portion on the forked member of the tool lifts the hinged cover plate away from the trailer's socket. The forked member is placed around the electrical connection adjacent the plug member and is pushed forward to lift the hinged cover plate. Once the hinged cover plate is lifted, the handle is pushed towards the motor vehicle, where the hooks engage lugs on the plug member, thus causing the plug member to separate from the electrical socket. Gripping grooves on the linear elements help to facilitate engagement between the tool and the lugs.

Abstract: A tool for disconnecting the air and electrical connections between a motor vehicle and a trailer or a utility hookup station includes a handle and a forked portion. A spring-mounted push bar extends away from the handle and abuts the electrical connection socket of the trailer. A lifting lug on one of the prongs of the forked portion of the tool lifts the hinged plate away from the trailer's electrical connection. The tool is placed around the electrical connection adjacent the trailer and is pushed upward until it engages the trailer plug. The handle is then pushed towards the trailer, forcing the plug on the motor vehicle away from the socket. Projections extending from the forked portion of the tool can be used to engage the air line connectors between a motor vehicle and a trailer or a utility hookup station to separate the air lines.
