Claim:
System for assembling a high-pressure fluid tube on a tubular pin, comprising: the tubular pin having a body, an annular groove adjacent the body, and an extending portion extending away from the annular groove; a fitting element having a metal bush crimped over the tubular pin with a radial flange extending into the annular groove of the tubular pin and the crimped bush extending over the extending portion of the tubular pin; an O-ring gasket in said annular groove that is distorted and tightly fixed between the radial flange and the tubular pin by the crimping of the bush, for sealing the bush to the tubular pin; the distortion of the gasket pressing the gasket against walls of said groove to create tightness between the radial flange and the tubular pin in the annular groove; and the high-pressure fluid tube being between the crimped bush and the extending portion of the tubular pin.
