The present invention relates to a structure for coupling a fitting for a hose assembly in which an assistant nut having one end engaged with a relative part adapted to supply a certain fluid using a rotatably supported nut and the other end used when engaging a coupling for a connection with a hose is detachably threaded to the fitting. In a structure for coupling a fitting for a hose assembly which includes a cylindrical hollow fitting which has an engaging jaw in one end of the same and through which a certain fluid such as a gas flows, a nut which has one end rotatably supported by the engaging jaw and the other end engaged with a relative part for supplying fluid, and a coupling which fixedly pressurizes the hose inserted into the other end of the fitting in a radial direction, there is provided a structure for coupling a fitting for a hose assembly which comprises an assistant nut which is disposed between the fitting and the coupling and in which a female thread corresponding to a male thread formed in an outer wall of the fitting is formed in an inner wall, and a circular groove is formed in an outer wall for thereby fixing the coupling.
