ABSTRACT:
The auxiliary device is in the form of a disk-shaped body having a front face, a rear face and lateral side wall surfaces. A cylindrical bore hole extends through the body from its front face to its rear face and it has a diameter that is slightly smaller than the outer diameter of the retractable spring-loaded sleeve of an air hose quick-disconnect coupling so that the auxiliary device may be manually slid on over the tubular sleeve and frictionally held thereto. The diameter of the front face of the disk-shaped body is sufficiently large enough that the hand of the person connecting or disconnecting the end of an air hose to the coupling can push his hand against the front face to move the spring loaded sleeve rearwardly while engaging or disengaging the end of the air hose.
