Claim:
A twistable hydraulic hose joint comprising: a sleeve including a first end, a second end, and a center passageway extending between the first and second ends, the first end having an abutment part extending radially from an outer surface of the sleeve with respect to a center axis of the center passageway; a tubular insert disposed inside the sleeve such that an annular hose receiving space is formed between the sleeve and the tubular insert; a flexible tube having an end portion disposed in the annular hose receiving space between the sleeve and the tabular insert; an O-ring disposed on the outer surface of the sleeve between an end face of the second end and the abutment part; and a fixing bolt including an external surface with an externally threaded portion and an internal bore, the internal bore having a first bore section disposed around the sleeve and a second bore section that is smaller than the first bore section to form an abutment surface that faces in an axial direction of the internal bore to abut against the abutment part within the internal bore, with the sleeve being disposed completely on one axial side of the abutment surface of the fixing bolt with respect to a center axis of the fixing bolt, the sleeve, the tubular insert, and the flexible tube being frictionally fixed together to twist as a unit relative to the fixing bolt.
