PURPOSE: A hose adapter is provided to prevent crack of interior rubber of a hose by restricting the longitudinal tensile strain of the interior rubber below the tensile elongation after aging. CONSTITUTION: A hose connection(10) includes a socket(12), a nipple(13), and a plurality of annular grooves(16). The nipple has a smaller diameter than the socket. The annular grooves are formed at regular intervals in the longitudinal direction on the outer surface of the nipple. A hose(30) is inserted between the socket and the nipple. The socket is deformed from the radially outer side to the inner side by swaging at various longitudinal positions(12a,12b) where the hose is fixed.
