Claim:
A pipe adjustment tool comprising: a flexible chain clampingly positioned about a pipe section; a frame comprising a cylindrical body, a threaded bore extending longitudinally and completely through said cylindrical body, and a base integral with and rigidly affixed to said cylindrical body and extending radially outward from said cylindrical body, said base having a seating surface seated against an exterior surface of the pipe section, said seating surface being disposed at a 45-degree angle relative to a longitudinal axis of said threaded bore, a first end of said flexible chain secured to said base; a retainer having a pair of spaced furcations defining an aperture; a retaining pin extending across said aperture of said retainer; a cam lock disposed within said aperture of said retainer at a spaced distance from said retaining pin through which a second end of said flexible chain is threaded and secured against being withdrawn from said aperture by said cam lock, said cam lock pivotally connected to said retainer for rotation between a first position where said second end of said flexible chain is compressed between said retaining pin and said cam lock, and a second position where said second end of said flexible chain is freely passable between said cam lock and said retaining pin; and a threaded bolt threadingly received entirely through said threaded bore and engaged with said retainer such that rotation of said threaded bolt draws said frame and said retainer together, thereby tightening said flexible chain about the pipe section.
