Abstract
A clamp used on pipe comprises a clamp having a body adapted to be positioned around the pipe having first and second ends, gripping members for engaging the pipe connected to the body and a screw member pivotally connected to the first end of the body for extending through a passageway in a member connected to the other end of the body. A wrench is used with the clamp for tightening the clamp portion around the pipe having a nut matingly engaging the threaded member to move the threaded member relative thereto, a handle for transferring a torque to the nut and apparatus connecting the nut to the handle, which has a ratchet for transferring the torque to the nut when the handle is turned in a first direction while permitting movement of the handle in an opposite direction without applying a torque to the nut.
