Abstract: A hose jacket for protecting a flexible resilient fluid conveying hose from external damage comprises a plurality of tubular segments formed of a synthetic resin that fit over the hose in end-to-end fashion with the segments having internal and external tapered surfaces at opposite ends, with the internal tapered surface of one segment mating with the external tapered surface of the adjacent segment so as to facilitate articulation of the hose and hose jacket while limiting gaps between the adjoining hose jacket segments. Connector fittings on the hose retain the hose jacket on the hose. A compression spring between the hose jacket and the hose fitting can be used for resiliently urging the segments together.
