"COUPLING SYSTEM FOR FLEXIBLE PIPES, FOR HIGH AND VERY HIGH INTERMEDIATE HYDRAULIC PRESSURES" and whose system consists of arranging that the coupling of the female bushing to the corresponding end of the conduit, is made without flushing rubber of the same, by means of threading it directly on said end, for which, the bushing, is constituted so that its interior threaded sector has a bit of edge on the crest of its first thread, to cause an advance only at medium distance, while the crests of the rest of the threads, they are arranged to be blunt, whereby, when introducing the spike into the bushing thus constituted, once it has been threaded on the end of the pipe, the outer mesh thereof is forced to impact against the windings. planes of the crest of the thread, which produces a strong and secure subjection.
