Abstract
An installation tool for expanding a locking sleeve for interlocking ends of the sleeve, the tool including a hydraulic cylinder driving a clamp or push block having at least one engagement surface parallel to an edge surface of one of the interlocking ends of the sleeve. More specifically, the clamp or push block includes a pair of engagement members having at least one engagement surface parallel to the edge of one of the interlocking ends of the sleeve. During use, an anchor extending from the cylinder is inserted within an aperture adjacent one interlocking end of the sleeve, and the engagement surfaces are abutted against the other interlocking end of the sleeve. Thereafter, the clamp or push block is driven by the cylinder to bear against the edge of such interlocking end of the sleeve, thereby expanding the sleeve until the ends of the sleeve interlock to lock the sleeve in a radially expanded sealing condition.
