An improved screw-on assembly for coupling line connectors with spouts has been invented. The invention can be used with bag-in-box packaging or with a variety of other applications requiring fluid coupling. In one embodiment, threading is accomplished by mating internal threads on a line connector with flexible tabs located on the spout. Deformation of the tabs during threading provides a restorative force that stabilizes the assembly during threading. Cooperation of the deformable tabs with structures near the end of the thread provides for self-locking of the assembly. In addition, the tabs are situated on a flange, providing compatibility of the present invention with prior art line connectors.

L'invention concerne un ensemble à visser amélioré destiné à coupler des connecteurs coaxiaux à des becs. L'invention peut s'utiliser dans l'emballage de cartons-outres ou dans de nombreuses autres applications nécessitant un accouplement hydraulique. Dans un mode de réalisation, le filetage est effectué par couplage de filets intérieurs sur un connecteur coaxial avec des languettes flexibles situées sur le bec. La déformation des languettes au cours du filetage fournit une force de restauration qui stabilise l'ensemble au cours du filetage. La coopération des languettes déformables avec des structures proches de l'extrémité du filet permet un auto-verrouillage de l'ensemble. Les languettes sont, en outre, situées sur un collet, ce qui rend la présente invention compatible avec des connecteurs coaxiaux déjà existants.
