ABSTRACT:
A permanently attachable coupling for high pressure multiple layer wire reinforced hydraulic hose in which the grip on the hose is achieved by the penetration of plural gripping teeth through the cover of the hose directly into engagement with the wire reinforcement. The coupling includes an overlapped shell arrangement in the region of at least one gripping tooth to provide a deeper penetration of that tooth into the reinforcement structure when the shell is crimped into engagement with the hose. The nipple structure of the coupling includes an annular gripping ridge in the region of the overlap which produces a pincer-like grip upon the hose.
