Abstract
A wrench comprising a handle carrying a flexible strap that is arranged as a loop with both of its ends anchored to the handle. A loop-adjusting slide is mounted on the handle for movement relative to the anchoring point and has the doubled ends of the strap slideably passing through it outwardly of the anchoring point so that movement of the slide adjusts the size of the loop. A ratchet is provided to hold the slide member in loop-tightening position and a spring returns it to its original position upon release of the ratchet.
