Abstract:
1. A tool for use in disconnecting a quick-connect air-hose coupler, the tool comprising: a pair of arms, each arm having a tool end and a handle, the arms hinged between the tool end and the handle, the hinge located inboard of the tool ends, 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 formed on each tool end, the rings being generally coaxial when the rings are adjacent to each other; and an insert configured for insertion into one of the rings, the insert comprising an opening of a selected width and a groove along an outer surface of the insert, the groove configured to engage the incomplete ring, such that the insert extends along the sides of the incomplete ring; wherein the handles are adapted to be moved toward each other for causing the rings to move away from each other while the rings engage 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; wherein the width of the opening of the insert is selected according to the diameter of the hose.
