The hose intermediate retainer comprises a tubular member having a flange-shaped portion, a ringlike groove and a plurality of vertical grooves (flutes). The vertical grooves (flutes) extend in the axial direction at circumferentially fixed intervals to an outer peripheral surface or an inner peripheral surface of the tubular member. With the hose inserted into the center hole of the tubular member, the tubular member is caulked (i.e., squeeze-formed) from all directions, with the result that the diameter of the center hole becomes sufficiently small and thus the hose is fixedly held by the retainer.
