ABSTRACT:
A hose fitting assembly has a fitting, a spool that translates into the fitting and a sleeve sliding along the spool onto the fitting. The fitting has a bore, an exterior channel, and apertures connecting the exterior channel to the bore. Disposed at the apertures are elements radially intrudable into the bore. An ring-like spring in the channel keeps these elements at the apertures and biases them into the bore. A bevelled part of the spool forces the intruding elements and spring out from the bore as the spool's plunger portion sealingly slides in the bore. The sleeve coacts with outward motion of the spring to lock the spool to the fitting, the sleeve aligned in its locking position on the fitting by a shoulder on the fitting.
