Claims

[Scope of utility model registration request]

The end of the hose is inserted into the outer periphery of the nipple at the tip of the tube, a socket made of a metal softer than the tube and having a cylindrical portion and a collar is placed on the outer periphery of the hose, and the socket is inserted in the inner diameter direction. In the hose connection device, the flange is press-fitted into the fitting groove formed in the tube body by applying pressure, and the cylindrical portion is deformed to connect the hose and the tube body. An annular protrusion is formed on the bottom of the socket to which the bottom of the socket is pressed, and a tapered protrusion protrudes toward the opening of the side of the fitting groove so as to be pressed against the side of the socket. A hose connection device characterized in that:
