A peristaltic pump includes a housing and a rotor that rotates about a rotor axis. The rotor has a rotor body and a pump. The housing has a cut-out in which the rotor is accommodated and a support surface extending about the rotor axis. The support surface supports a tube segment that is introducible between the rotor and support surface. The rotor has a first element for manually actuating the rotor and a first portion for applying a manual rotation actuation force. The first element is mounted on the rotor body and is movable relative to the rotor body between a first position, in which the first portion is spaced from the rotor axis by a first length, and a second position, in which the first portion is spaced from the rotor axis by a second length, the second length being greater than the first length.
