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.

Hose fitting having ferrule anti-rotation ratchet teeth

Unitary cartridge of plastic material for discharging a pyrotechnic mixture, smoke flare, chaff round, and the like is disclosed. A slidable piston is contained within a hollow casing forming the cartridge to engage with a portion of the casing to provide an internal integral seal for sealing a replaceable impulse cartridge and/or blank plug therein. A moisture proof seal is thereby maintained when the cartridge is armed by the insertion of an impulse cartridge or downloaded by the insertion of a blank plug. To facilitate the assembly of the cartridge, a rupturable closed end is provided with an internal lip adapted for engagement with an end plug to facilitate its alignment and positioning therein.
