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.

The valve includes a valve seat and a valve body with a circular diaphragm. The valve body is arranged over the valve seat in order to close the latter sealingly when it bears on the valve seat. The valve seat and the valve body have openings which are offset relative to one another and which form a free passage when the diaphragm of the valve body lifts. The diaphragm of the valve body has elongate openings which are uniformly distributed along a circle in the periphery of the diaphragm, the circle having approximately the same center point as the diaphragm. The elongate openings are separated from one another by webs, the diaphragm being designed to be weaker in the area adjacent to these webs.

The invention relates to a disposable breast cup set which comprises a coupling element () to be coupled to a milk collection receptacle () and a breast cup connecting element () to be coupled to a breast cup funnel (). The coupling element () and the breast cup connecting element () are interlinked via a tamper-evident element (), said connection being destroyed when the coupling element () is for the first time separated from the breast cup connecting element () and preventing re-use of the set.
