Hose coupling

In a coupling member for hoses, a flexible coupling section having a central bore of a diameter substantially equal to the outside diameter of said hose and adapted to fit over the end segment of said hose, said coupling section including a threaded portion for coupling said member to a mating coupling section, said bore being defined by an interior cylindrical wall within said coupling member, a series of annular barbs formed in said cylindrical wall and defining spaced apexes separated by recessed areas, said annular barbs having a reverse rake angle, each said barb comprising a base sloping rearwardly and outwardly to a juncture with a radial wall extending inwardly and forwardly therefrom, said juncture defining a said apex, said apexes being longitudinally aligned along lines parallel to the longitudinal axis of said central bore, and a tubular ferrule within the interior of said end segment urging the wall of said hose section outwardly into said barbs, said tubular ferrule including a central passageway having a cross-sectional area substantially equivalent to the interior passage of said hose, and an annular rib projecting toward a said recessed area between apexes of said barbs.
