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.
