CA 2468656

The invention relates to a plug-in connector comprising a base body (6), an annular sealing element (12), a clamping ring (50), and a ring body (20) which can be connected to the base body (6). A tube end (4, 5) against which the sealing element (12) is arranged in a sealing manner can be tightened in the plug-in connector by means of the clamping ring (50). The aim of the invention is to improve one such plug-in connector in such a way that it can be connected to the at least one tube end (4, 5) in a simple manner and with high functional safety, excluding the risk of assembly errors. To this end, the sealing element (12) which is arranged in an annular groove (14) of the base body (6) comprises two sealing beads (60, 62) which are located against the inner surface of the inserted tube end (4, 5), in the form of two O-ring type seals.

Raccord enfichable qui comporte un corps de base (6), un élément d'étanchéité annulaire (12), une bague de serrage (50) ainsi qu'un corps annulaire (20) pouvant être relié au corps de base (6), une extrémité (4, 5) de tuyau contre laquelle l'élément d'étanchéité (12) repose de manière étanche pouvant être serrée dans le raccord enfichable à l'aide de la bague de serrage (50). L'objet de la présente invention est d'améliorer ce raccord enfichable de manière que la liaison avec l'extrémité (4, 5) de tuyau au moins puisse être réalisée de manière simple et présenter une haute sécurité fonctionnelle, le risque d'erreurs de montage étant exclu. A cet effet, l'élément d'étanchéité (12) placé dans un évidement annulaire (14) du corps de base (6) possède deux bourrelets d'étanchéité (60, 62) qui appuient, à la manière de deux joints toriques, contre la surface interne de l'extrémité (4, 5) de tuyau dans laquelle le raccord est introduit.
