A device for joining detachably a tubular member such as a hose, a pipe or the like to a main body which has at its end a cylindrical pipe and a flange which is formed along the outer periphery of said cylindrical pipe and whose peripheral surface is formed with screw threads. One end of an inner cylindrical pipe is connected to the flange of said main body in such a way that the inner cylindrical pipe may freely rotate about said cylindrical pipe. The inner cylindrical pipe is formed with a plurality of through holes which are circumferentially spaced apart. And an annular space is radially defined between the inner cylindrical pipe and the cylindrical pipe of said main body. Rolling elements are rotatably fitted into respective through holes of said inner cylindrical pipe. After said tubular member has been fitted into said annular space, an outer pipe is threadably engaged with the flange of said main body so that the tapered surface formed on the inner surface of the outer pipe may force the rolling elements radially inwardly, thereby clamping said tubular member between the cylindrical pipe of said main body and said rolling elements so as to join said tubular member to said main body.
