Pipe joining and disjoining tool which includes an operating lever having a yoke at one end. Another yoke is pivoted to the yoke on the operating lever, for mounting the tool on one of the pipes to be joined. A chain is secured to the other pipe, and extends upwardly through a passageway in the operating lever. To join the pipes, the chain is tautened and locked in a slot at the top of the operating lever, which is then swung downwardly to tightly draw the pipes together. For disjoining pipes, the tool includes a disjoining member having a third yoke which is mounted on the yoke on the operating lever and which can be pivotally moved away from the operating lever. The chain is pulled taut and is locked in a slot in the disjoining member, and the pipes are disjoined by swinging the operating lever in a direction opposite the direction of swinging for joining the pipes.
