Abstract: A wrenching tool with an anchored flexible strap that is placed around the rotating part of a screw type connector, the strap then being slide fitted and adjusted in one of two angular slots on the tool for the purpose of tightening or loosening the connector. With proper fitting and adjustment of the strap, a rotation of the tool, which is generally parallelingly in line but offset from the axis of the connector, causes a bight by the strap being restricted on the connector that will, depending on the slot used, tighten or loosen the connector.
