Abstract
A hollow elongate tube surrounds an elongate rod intermediate its proximal and distal segments. A resilient deformable seal surrounds the distal segment. The seal is secured to prevent movement of the seal in a forward direction off the distal segment of the rod. A cam mechanism is connected to the proximal segment of the rod and is movable to pull the rod in a rearward direction through the tube to squeeze the seal in an axial direction. This causes the seal to expand in a radial outward direction against an inner wall of a pipe into which the seal has been inserted. A lever is connected to the cam mechanism to facilitate manual movement of the cam mechanism to expand the seal.
