  • Coupling for non-metallic hose
    Patent number: 4150848
    Abstract: A hose coupling is provided which is comprised of two semi-circular coupling halves bolted together around the outer surface of the end of a non-metallic hose. The inner surface of each coupling half is provided with a metal plate having a multiplicity of prongs struck from the metal of the plate to extend radially inwardly for penetrating the non-metallic hose. All of the prongs extend circumferentially of the hose to facilitate penetration of the hose during assembly of the coupling halves and to maximize retention of the coupling on the hose end.
