The present invention relates to a pinch valve ( 1 ) with a housing which has an inlet ( 2 ), an outlet ( 3 ) and a control opening ( 4 ) for connection to a pressure medium, inlet and outlet being connected to each other via a passage, the passage having at least two sections with a different cross-section ( 12 ), and a valve sleeve ( 16 ) which is connected to the inlet and outlet and arranged such that it forms a valve channel between inlet and outlet, the valve sleeve ( 16 ) moving, upon application of a pressure medium to the control opening ( 4 ), such that the channel cross-section between inlet and outlet is reduced or closed. In order to provide a pinch valve can be produced simply and at favourable cost and also seals reliably, it is proposed according to the invention that the housing is formed in at least two parts, one housing part forming the section with a smaller passage cross-section and the other housing part forming the section with a larger passage cross-section.
