A fuel hose (10) has a straight insertion end portion (l0a) at one axial end thereof and includes an outer layer (11) formed of a cylindrical elastic rubber body and having a groove portion (12) formed coaxially on the inner wall at an axially inward end of the insertion end portion (l0a); a thin-walled inner layer (18) made of a resin material of low gasoline permeability and fixedly bonded to the entirety of a portion of the inner wall of the outer layer, the portion including at least the groove portion and extending axially inward from the groove portion; and an annular seal member (19) fitted tightly into the groove portion lined with the inner layer. A mating pipe (21) having an engagement protrusion (22) formed at an end portion thereof is inserted under pressure into the insertion end portion of the outer layer such that the engagement protrusion presses the seal member fitted into the groove portion to thereby be engaged with the groove portion in a fluid-tight condition. A ring- shaped clamp member (25) is mounted on a clamp portion (16) of the outer layer (11) for clamping.
