ABSTRACT:
A sewer line coupling device to facilitate attachment of a recreational vehicle sewer line to a fixed waste pipe. The coupling device comprising a main body having a second end for insertion into the waste pipe. A movable member is movable relative to the main body and a sealing sleeve is supported by the main body adjacent the second end. One end of the sealing sleeve is affixed to the main body while the other end is coupled to the movable member. When the movable member is moved in a first direction, a minimum dimension of the sealing sleeve is achieved to facilitate insertion into the waste pipe and, when the movable member is moved in an opposite direction, a maximum dimension of the sealing sleeve is achieved to facilitate formation of a seal with the waste pipe. A flange is supported by the main body between the first end and the second end thereof.
