PROBLEM TO BE SOLVED: To provide a joint member which prevents a nut member from coming off a joint body, while enabling a nut member connecting operation to be inexpensively performed with ease. SOLUTION: This joint member, which is connected and fixed to another member by means of the annular nut member 4, includes: the tubular joint body 1; a flange portion 2 which is provided in such a manner as to protrude on a side surface of the joint body; an elastic locking portion 3 which is provided integrally with the joint body 1, and which reduces a diameter to the side of the center of the joint body by undergoing stress; and the nut member 4 for connecting and fixing the joint body 1 to another member, through which the elastic locking portion 3 can be inserted in the diameter-reduced state of the elastic locking portion 3, and through which the elastic locking portion 3 cannot be inserted in the diameter-unreduced state of the elastic locking portion 3.
