ABSTRACT:
The exhaust coupling of the invention comprises a first length of tubing having a first assembly flange fixed thereon, a second length of tubing associated with a second assembly flange, clamping means disposed to urge the assembly flanges towards each other via first resilient members, and second resilient members disposed between the assembly flanges in order to be compressed therebetween and to exert a force on the flange which is less than the opposing force exerted thereon by the first resilient members.
