Abstract
A hydraulic hose having a core tube, a layer of reinforcing material disposed about the core tube and a protective sheath about the reinforcing material is provided with a coupling member on one end thereof having a nipple inserted in the core tube and a shell disposed about the sheath of the hose. The shell has a plurality of circumferentially spaced integral solid three-dimensional barbs piercing the sheath and embedded in the reinforcing material. The barbs are preferably either conical or pyramidal and have a pointed apex in order that they can pierce the reinforcing material when the coupling member is installed on the end of the hose by insertion between fibers without cutting or tearing the reinforcing material.
