The hose pump has a hose (6) with enlarged cross section (4) in the entry region (5) of the pinching device (3,7). The hose is pinched against the casing by the rotating pinching devices on a rotary body (2). To prevent the fluid flowing back from the exit side (8) to the hose, a greater supply volume is provided by the enlarged cross section in the entry region.
