ABSTRACT:
A manually operated tool engages and draws towards one another opposed spaced flanges of a repair clamp disposed about a leaking pipe for moving the clamp into position and securely maintaining the clamp on the pipe over the leak allowing plural nut and bolt combinations on the clamp to be tightened in sealing off the leak. A movable handle has attached thereto first and second pivoting arms adapted for respectively engaging a slot within the clamp's first edge flange and the outer edge of the clamp's second opposed edge flange when the handle is in a first non-use position. Moving the handle to a second use position urges the clamp's edge flanges toward one another drawing the clamp securely about the pipe, allowing the clamp's nut and bolt combinations to be tightened. The tool is adjustable for use with a wide range of clamp sizes and pipe diameters.
