ABSTRACT:
A hose having an orifice is disclosed. The hose comprises a nipple which is provided in one part of the inside of the hose for the purpose of forming an orifice; a sleeve which is fitted over the outer surface of the hose at a position corresponding to the nipple, the sleeve having a caulking portion for fixing the nipple such as to make it axially unmovable, and the caulking portion being shorter than the length of the nipple; and at least one pair of protrusions which are formed on the outer peripheral surface of the nipple, and which are retained by the inner surface of the hose and prevent the nipple from moving, the protrusions being situated at both ends of the nipple at positions which do not correspond to the caulking portion.
