ABSTRACT:
A coupler for connecting a hose to an engine exhaust duct for conveying products of combustion to the outside of an enclosed area. Permanent magnets enable mounting of the coupler to be quickly made. A handle spaced from the coupler bracket enables the magnetic attraction between the coupler and the engine block to be broken without touching the hot metal. A spring tensioned gas tube is urged into engagement with the engine exhaust duct when the coupler is in operative position.
