A tool for joining plastic pipe and fittings that provides for a quarter turn rotation of a pipe fitting while simultaneously pulling a free end of a longitudinally aligned pipe section into the fitting. The tool includes an inner ring that slips over a free end of a pipe section and is secured thereto by inwardly directed mounting screws, and an outer ring coaxially circumposed about, and rotatably connected to, the inner ring. A detachable semicircular partial collar fits snugly about the outer ring and reversibly attaches to a pair of outwardly directed nibs positioned on opposite sides of the outer ring in a plane that bisects the pipe section. A crossbar is mounted between a pair of lugs attached to a central portion of the partial collar. A handle is pivotally mounted above a yoke and chain that encircle and grasp the fitting. Drawbars pivotally mounted to a lower end of the handle engage the crossbar so that longitudinal movement of the handle applies a longitudinal force equally to opposite sides of the pipe section, and rotation of the handle causes the fitting to twist about a longitudinal axis. |
