Abstract: A trailer tongue extension assembly that includes a tubular trailer tongue, a removable extension, a first electrical connector disposed within the trailer tongue and a second electrical connector disposed within the removable extension. The first and second electrical connectors engage and disengage as the removable extension is installed or removed from the trailer tongue. A tongue pin is inserted either through registered holes in the tongue and the installed extension, or through aligned holes in the trailer tongue. A lock assembly secures the pin in the holes to, respectively, lock the extension on the trailer tongue or prevent the extension from being installed in the trailer tongue. Opposite ends of a lanyard or elastic member are attached to the pin and the trailer tongue, respectively, and resist the removal of the pin from the aligned holes.
