CA 2704763

The device according to the invention for connecting a suction hose (3) has a connecting piece (10) which is designed in such a way that the suction hose (3) can be pushed over a region of the connecting piece (10) in a sealing manner. The device also comprises a sleeve (2) which can be pushed over the aforementioned region of the connecting piece (10), at least partially covering said piece and leaving room between the sleeve (2) and the connecting piece (10) for the suction hose (3). The connection between the sleeve (2) and the connecting piece (10) can only be separated by the destruction of at least one of said two parts. The design of the exterior of the sleeve (2) prevents a second suction hose from lying in a sealing manner against the sleeve (2). A suction hose (3) that is connected in a sealing manner to the claimed device can therefore not be removed without destroying the device. In addition, it is impossible to push a hose with a greater diameter onto the sleeve (2) in a sealing manner.

L'invention concerne un dispositif de raccordement d'un conduit souple d'aspiration (3) présentant une tubulure de raccordement (10) configurée de façon que le conduit d'aspiration (3) puisse être emboîté de manière étanche sur une zone de la tubulure de raccordement (10). Le dispositif comprend en outre un manchon (2) pouvant être emboîté sur la zone précitée de la tubulure de raccordement (10) et recouvrant celle-ci au moins partiellement, tout en laissant un espace pour le conduit d'aspiration (3), entre le manchon (2) et la tubulure de raccordement (10). Le manchon (2) et la tubulure de raccordement (10) ne peuvent être séparés que par destruction d'au moins l'un de ces deux éléments. Le manchon (2) présente une configuration de surface extérieure qui empêche une application étanche d'un second conduit d'aspiration sur le manchon (2). De cette façon, un conduit d'aspiration (3) connecté étanche au dispositif selon l'invention ne peut pas être retiré sans qu'il y ait destruction du dispositif. De plus, aucun conduit de plus grand diamètre ne peut être emboîté de manière étanche sur le manchon (2).
