ABSTRACT:
An apparatus for outwardly radially compressing a gasket into sealing engagement with a wall of an opening includes a continuous strip of resiliently flexible material having first and second ends and first and second members. The first and second members are made from a different material than the strip and are respectively attached to the first and second ends of the strip to thereby form a ring. The first and second members are configured to include locking structure that both fixes the ring in an expanded position adjacent to the gasket and secures against contraction of the ring by the gasket. The apparatus may be made from a plurality of continuous strips of resiliently flexible material and have structure for aligning and securing the first end of each one of the strips adjacent the second end of another of the strips to form a closed ring. The aligning and securing structure includes at least one set of the first and second members.
