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.

Abstract: A cargo securing system comprising an elongate base member having a front surface and a rear surface with a plurality of attachment holes to facilitate attachment of the base member to a desired surface. An elongate slot is formed in base member and the slot communicates with an elongate recess. At least one adjustable member, having an enlarged head and a leg extending from the head, is accommodated by the recess. The head of the adjustable member is sized to slide along the recess of the base member with the leg projecting through and being freely slidable along the slot to facilitate sliding movement of the adjustable member relative to the base member. The base member carries a first interlocking structure and the adjustable member carries a mating second interlocking structure. When the first and second interlocking structures engages with one another, the adjustable member is retained at a desired position relative to the base member.
