1. A roller pump, comprising:
a pump head, comprising:
a pump rotor; and
a plurality of rollers rotatably supported by the pump rotor;
a tube retention device, comprising:
a tube retention block having a first wall surface facing a first direction and a second wall surface spaced apart from the first wall surface, the second wall surface facing a second direction opposite the first direction;
a first pin extending from the first wall surface;
a second pin extending from the second wall surface;
a first tube clamp including a first clamp component and a second clamp component;
the first clamp component of the first tube clamp pivotably coupled to the first pin such that the first clamp component is configured to rotate about an axis of the first pin; and
the second clamp component of the first tube clamp pivotably coupled to the second pin such that the second clamp component is configured to rotate about an axis of the second pin; and
wherein the first and second clamp components of the first tube clamp are configured to rotate, in opposite directions and in response to application of force by a tube piece upon the first and second clamp components, from an open position to a closed position, wherein the tube piece is retained between the first and second clamp components of the first tube clamp when the first and second clamp components of the first tube clamp are in the closed position.
