摘要： An assembly is provided that includes first and second end plates adapted to be coaxially aligned when in use. One or more members extend from the end plates or an annular ring, the annular ring provided between the end plates, the other of the end plates or annular ring comprising one or more first slots at one end thereof to be aligned with and for receiving the one or more members of the first end plate, and one or more second slots at the other end thereof to be aligned with and for receiving the one or more members. Resilient sealing members are provided around the one or more members between the end plates and annular ring, and an urging mechanism urges the first and second end plates towards the annular ring to deform the first and second resilient sealing members to engage the inner wall of the pipe.
