A coupling device having a first member (1) provided with threads (12), a second member (15) having an opening into and out of which the first member is inserted and removed, threaded elements (28) within the second member mounted for movement between a first position where the first member may be threaded with the second member and a second position where the threaded ele- ments have a diameter larger than the diameter of the threads of the first member, pins (33) associated with the threaded elements and a manually operable mechanism (18) for moving the threaded el- ements longitudinally into engage- ment with the pins expanding the threaded elements to their second position. The second member in- cludes an outer body (16) provided with oval openings (34) through which the pins pass.
L'invention porte sur un dispositif de couplage possédant un premier élément (1) à filets de vis (12), un second élément (15) pourvu d'un orifice d'entrée et de sortie et par lequel est inséré et retiré le premier élément, des éléments filetés (28) se trouvant dans le second élément qui est monté de façon à se déplacer entre une première position dans laquelle le premier élément peut être vissé avec le second, et une seconde position dans laquelle les éléments filetés ont un diamètre supérieur au diamètre des filets de vis du premier élément, des goupilles (33) associées aux éléments filetés et un mécanisme à fonctionnement manuel (18) permettant de déplacer les éléments filetés longitudinalement de sorte qu'ils viennent en contact avec les goupilles, ce qui permet l'expansion des éléments filetés dans leur seconde position. Le second élément comporte un corps externe (16) pourvu d'orifices de forme ovale (34) par lesquels passent les goupilles.
