An improved hose has a TPE cover layer disposed radially over an inner tube layer and reinforcing braid layer. A D-profile spiral guard is disposed atop the cover layer with a flat side of the D profile facing the cover layer. Hose connectors or end couplings are designed to be tough and durable, and not crush and deform in rough use. The hose end couplings are each retained with an external ferrule having internal spiral lands and grooves so that the spirals of the ferrule follow the spiral guard, to form an interference fit on the cover layer and spiral guard of the hose.
