Coupling device for semi-rigid pipes, of the type used especially for the coupling of hoses that must resist fluids at high pressures, characterized by being constituted by a bushing that is, for almost its entire length, of a general polygonal section that is reduced gradually in a frusto-conical portion, ending at one end with circular section, while internally the bushing is divided into five distinctly differentiated zones, the first of which, corresponding to the external circular section and apart from the truncated cone portion said external, is circular in section and is threaded for coupling to the fluid supply source; the second zone, somewhat shorter than the first, is of circular section of greater diameter than this one and is separated from it by a sharp step; the third zone is frustoconical and serves as a junction between the second and fourth zones, the latter being of cylindrical section and of greater diameter than that of the second zone; and the fifth zone is also frustoconical and has its external diameter greater than the internal one, being made a thread of broad fillet and section in mid-bocel, which rises sensibly in the line of separation between the second and third zones and dies before arriving to the outer limit of the fourth zone.
