Abstract

A hose pump for delivering fluids includes a housing having a base body and a cover. A pump body for delivering a fluid is rotatably disposed in the interior of the base body about an axis. A locking device is disposed on the housing in order to release and lock the cover. The pump body comprises a plurality of rollers disposed at the circumference of the pump body and delivering a fluid present in a hose by rotating the pump body. The rollers clamp the hose against an inner surface of the cover, and the locking device is attached captively to the base body and displaceably relative to the base body, and can be actuated single-handedly. The cover is attached captively to the base body and displaceably relative to the base body of the housing, and can be actuated single-handedly.
