The present invention refers to a system for assembling a high-pressure fluid tube (1) on a tubular pin (5), which is part of a fitting element (2) provided to be used in particular on motorcycles and motor-vehicles, for example for the production of pipes intended for manufacturing braking circuits or other circuits, in which high-pressure oil or other fluids flow. In particular, the invention relates to a system for assembling a high-pressure fluid tube (1) of the kind comprising a first inner layer (6) made of plastic, a second layer (7) made of a steel plait or other suitable material such as fibres or the like, a third coating layer (8), if any, made, for instance, of plastic material and a bush (9) made of steel, alloy or other material, fitted onto an end of the said tube (1), this tube (1) being fitted on the pin (5) and locked by caulking of the said metallic bush (9).; During caulking, the end of the bush (9) is distorted in an annular groove (10) of the pin (5) so that the O-ring (11) placed therein is tightly pressed against the walls of the groove (10).
