1. A peristaltic pump, comprising:
(a) a pump base;
(b) a rotor mounted to said pump base, the rotor having a conduit engaging side for engaging a flexible conduit;
(c) a cover member including a conduit backing side, the cover member being selectively moveable relative to the pump base between a working position and a released position, in the working position the conduit backing side being proximal to the conduit engaging side of the rotor such that the rotor pumps fluid through the flexible conduit, in the released position the cover member being distal to the conduit engaging side allowing removal of the flexible conduit from the peristaltic pump;
(d) the conduit backing side and the conduit engaging side defining a pumping interface at which fluid contained in the conduit is displaced through the conduit by the rotor;
(e) a conduit retainer mechanism for engaging the flexible conduit to assist with retention of the flexible conduit against displacement resulting from engagement between the flexible conduit and the rotor, the conduit retainer mechanism including a first component and a second component;
(1) the first component being mounted to the pump base;
(2) the second component being mounted to the cover member, the first and the second components being configured to cooperate to engage the flexible conduit there between when the cover is moved to the working position; and
(3) the first and the second components being configured to cooperate to engage the flexible conduit at a location that is remote from the pumping interface, wherein
the conduit retainer mechanism includes a resilient component that resiliently acts against the flexible conduit.
