Patent attributes
A tool for use in disconnecting a quick-connect air-hose coupler has a pair of arms, each arm having a tool end and a handle, the arms being hinged to each other for relative rotation in generally parallel planes, such that selected relative movement of the handles causes opposite relative movement of the tool ends. An incomplete ring is formed on each tool end, the rings being generally coaxial when the rings are adjacent to each other. An insert is configured for insertion into one of the rings, the insert comprising an opening of a selected width. The handles are able to be moved toward each other for causing the rings to move away from each other while the rings engage an air-hose coupler and a hose, so as to cause the insert in one of the rings to abut a movable sleeve of an air-hose coupler while other of the rings abuts an apparatus fixedly engaging the hose, so that when sufficient force is applied to the handles the sleeve is moved relative to a body of the coupler and to the hose for disconnecting the coupler from the hose. The width of the opening of the insert is selected according to the diameter of the hose.
