摘要:
The device according to the invention for connecting a suction hose has a connecting piece which is designed in such a way that the suction hose can be pushed over a region of the connecting piece in a sealing manner. The device also comprises a sleeve which can be pushed over the aforementioned region of the connecting piece, at least partially covering said piece and leaving room between the sleeve and the connecting piece for the suction hose. The connection between the sleeve and the connecting piece can only be separated by the destruction of at least one of said two parts. The design of the exterior of the sleeve prevents a second suction hose from lying in a sealing manner against the sleeve. A suction hose 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 in a sealing manner.
