A fluid coupling for coupling a hose to a metal tube, of primary interest in hydraulic brake systems, provides dynamic strain relief so that hoses having braided reinforcing layers are made usable for normal highway use because the hoses can withstand Department of Transportation Whip Test while meeting thermal requirements. This is accomplished by a coaxial strain relief element which is integral with an eyelet-type tube. fitting wherein the strain.relief element is captured by a pocket disposed in the end of a crimping cup. A crimping cup directly engages the braided reinforcement layer to clamp the hose against a projecting nipple of the eyelet while having an annular lip portion which seats in the groove in the eyelet and presses the coaxial strain relief element into and direct engagement with the braided reinforcement layer.
