To provide a wrench for pipe joints which smoothly rotates the joint in a desired direction without scratching or leaving any linear holding trace by firmly holding outer circumference of a pipe joint.

The wrench is provided with a fork-shaped holding section 2 holding a elbow part periphery of a L-shaped pipe joint throughout its lengthwise direction, and a fitting hole 6 into which an operating handle is detachably engaged. In this wrench, the rotary torque of an operating handle is transmitted to the entire elbow part surface of the L type pipe joint through the holding section 2, thus the L-shaped pipe joint is easily attached/detached to/from a conduit end.
