Abstract
A disconnection tool for disconnecting pipes which are connected. The disconnection tool is preferably a two piece cylinder with a leading edge and handles opposite the leading edge, and, can be positioned around a male end of a male pipe that is within a female end of a female pipe. The disconnection tool initially inserts into a clearance between the interior surface of the female end and the exterior surface of the male end while the pipes are connected. As the disconnection tool is further inserted, its leading edge contacts and disengages one or more locking members extending through the clearance thereby allowing the male pipe to be disconnected from the female pipe.
