A plumbing tool having a ring with a circular structure defining an opening that extends through the circular structure. The circular structure is formed with a slot, and a pair of threaded apertures are disposed on opposite sides of the opening in order to communicate with the same. Each of the threaded apertures terminate in a recess disposed within the circular structure and communicating with the respective threaded aperture. A bolt threadably passes through the pair of threaded apertures for winding and narrowing the opening. A second pair of threaded apertures extend through the circular structure in a generally opposed relationship for threadably receiving a pair of handles.
