7/254210
Inventors:
Fredric J. Hohman - Altoona WI

Abstract:
A coupling device for releasably attaching an exhaust hose to the tail pipe of an internal combustion engine to conduct exhaust from an enclosed work space to the atmosphere. The coupling device is characterized by a pair of finger-like opposed spring members cantilever mounted inside a tubular coupling member at points spaced from one end, each extending longitudinally beyond one end of the tubular section and each biased outwardly against the inside surface of the tubular coupling member. The finger-like members are urged inwardly against their bias and inserted into the tail pipe as the coupling member is placed over the end of a tail pipe in a female-male relationship, releasably securing the coupling device in sealed relationship with the tail pipe.
