PROBLEM TO BE SOLVED: To provide a fixing method for metal fittings or a plastic case and the like to be attached at the end of a flexible tube or pipe. SOLUTION: The end of a cylindrical flexible tube 1 is pressed and deformed and the receiving side is constructed with the fitting of an upper case 6 and a lower case 7. A cavity part 4 to receive the deformed part of the end of the flexible tube 1 is provided. In fixing the flexible tube 1 and the upper and the lower cases 6, 7, a protrusion 5 for fitting is provided inside or a ring 3 with threads inside is used. The flexible tube 1 is passed inside and the protrusion 5 is received by a receiving groove 8 or tightened by a screw to be fixed in the upper and the lower cases 6, 7. In this case, as the connected part of the flexible tube 1 and the cases 6, 7 are along the crushed shape of the end of the flexible tube 1, the turning of the flexible tube 1 to the direction of outer circumference (A direction) can be avoided.
