ABSTRACT:
A hose fitting for permanent attachment to a flexible hose such as a garden hose. The fitting includes a tubular member having helical barbs or threads on an outer surface portion thereof for allowing the tubular member to be firmly held within an open end of the hose and to further form helical deformations in the hose. The fitting further includes a ferrule having similar helical barbs or threads on an inner surface thereof for allowing the ferrule to be threaded over the hose end having the helical deformations formed by the tubular member inserted therein. The tubular member and the ferrule include mating ratchet teeth which lock together when the ferrule is threaded over the deformations in the hose end such that the fitting is permanently attached to the hose. The tubular member includes a coupling portion on its outer end for allowing the hose fitting to be attached to another fitting or a fluid device such as a faucet or lawn sprinkler. The tubular member and ferrule are both preferably formed from polymeric material.
