Claim:
Switching device comprising: a support ( 20 ) provided with positioning guides ( 22 ) defining a first location adapted to receive a first inlet flexible tube, a second location adapted to receive a second inlet flexible tube and a third location adapted to receive an outlet flexible tube, said support being further provided with a first stop ( 24 a ) and a second stop ( 24 b ) within the first and second locations respectively, and a cover ( 32 ) comprising two compression elements ( 34 a , 34 b ), each compression element being adapted selectively to squeeze an inlet flexible tube against a stop, when an inlet flexible tube is in the first or second location, wherein said first and second locations extend along a first axis, and said cover ( 32 ): is pivotable about an axis (x–x′) parallel to said first axis, between a working position, in which the compression elements are facing the first and second locations, and a rest position, in which both compression elements are away from the first and second locations, and is slidable along said first axis, the compression elements being arranged such that at least one compression element is always facing a said stop.
