In order to improve a pump hose that is suitable for a peristaltic pump whereby transitions within the hose are avoided and which furthermore is operationally reliable, there is suggested a pump hose having a tubular center part (11) to which are arranged at both sides thereof connecting parts (12, 14) for connecting the pump hose (10) to other elements and having flange parts (17, 18) arranged at both sides for insertion into a cartridge part of the peristaltic pump. The tubular center part (11), the connecting parts (12, 14) arranged at both sides thereof and the flange parts (17, 18) arranged at both sides thereof are integrally produced from silicone. The connecting parts (12, 14) each have a head-like shaped sealing surface (16). The sealing surface (16) is surrounded by a substantially circular sealing bulge (20) that protrudes longitudinally beyond the sealing surface (16). The flange parts (17, 18) comprise nubs (22) whereby the pump hose (10) is inserted in a non-gas-tight manner, preferably also in a non-fluid-tight manner, into the peristaltic pump segment.
