A cartridge for a peristaltic pump comprises two parts having a frusto-conical bore extending through the two parts and a dovetail section groove encircling the bore at the joint between the two parts. A liquid carrying tube extends into the cartridge and has a convolution encircling the bore. The tube has an integral dovetail section rib extending along the length thereof which engages in the dovetail section groove encircling the bore to locate the tube in the bore. The cartridge is used with a pump having a rotor with one or more rollers mounted eccentrically thereon to rotate about axes convergent with the rotor axis. The rollers compress and flatten the tube where they engage it so that as the rollers rotate around the bore in the cartridge, liquid in the tube is displaced along the tube in a continuous flow.
