The roller pump has a tube (12) with an abutment support, squeezed by a pressure roller (13), located along the tube. The hand lever operated pressure roller is movable to and from, relative to the extension of the tube. Also on one of the movement tracks (I,II), it returns from its squeezing position to the tube. The pressure roller is taken through a window, lying at an angle to the extension, by a hand swivel lever (14) in such a manner, that it enters in one movement track (I) in the squeezing position at the tube, and in the other movement track (II), is removed from this position.
