A device for connecting flexible hoses comprises a connecting member (2) having a tubular element (4) that can be inserted into a flexible hose (T) . The tubular element (4) and a radially external threaded cylindrical member (5) together delimit an annular seat (7) designed to accommodate an end (T1) of the flexible hose (T) . A threaded ring (10) can be screwed onto the cylindrical member (5) and accommodates a split bush (15) having a working surface (16) engaged with a working surface (14) of the ring (10) . By turning the threaded ring (10) , the split bush (15) can be moved between a position where it is axially spaced from the threaded cylindrical member (5) and a position where it is axially close to the threaded cylindrical member (5) and where an interposed seal (18) between the cylindrical member (5) and the bush (15) adopts a radially inwardly deformed condition such as to tighten it around the flexible hose (T) .
L'invention concerne un dispositif permettant de connecter des tuyaux souples, qui comprend un élément de connexion (2) composé d'un élément tubulaire (4) pouvant être introduit dans un tuyau souple (T). L'élément tubulaire (4) et un élément cylindrique (5) à filetage radial externe délimitent ensemble un siège annulaire conçu pour héberger une extrémité (T1) du tuyau souple (T). Une bague filetée (10) peut être vissée sur l'élément cylindrique (5) et recevoir une douille de serrage (15) dotée d'une surface de travail (16) qui coopère avec une surface de travail (14) de ladite bague (10). Lorsqu'on tourne la bague filetée (10), la douille de serrage (15) peut se déplacer d'une position dans laquelle elle est axialement espacée de l'élément cylindrique (5) fileté vers une position dans laquelle elle est axialement proche dudit élément cylindrique (5) fileté, un joint interposé (18) entre l'élément cylindrique (5) et la douille de serrage (15) adoptant un état radialement déformé vers l'intérieur, ce qui le resserre autour du tuyau souple (T).
