1. An assembly configured to position a peristaltic tube with respect to a linear peristaltic pump drive of an infusion pump, the assembly comprising:
a frame, configured to be releasably coupled to the infusion pump such that the peristaltic tube is placed in contact with the linear peristaltic pump drive;
a first tube coupler and a second tube coupler, each configured to be connected to opposing ends of the peristaltic tube and each having a lumen in fluidic communication with the peristaltic tube, wherein the frame is fixedly coupled to both the first tube coupler and the second tube coupler;
a free-flow prevention arm hingedly coupled to the frame and having a latching structure configured to cooperate with a latching receiver of the frame, the latching structure including a thumb press surface oppositely-disposed of the latching receiver and a release catch offset a distance from the thumb press surface, the free-flow prevention arm configured to alternate between a closed position and an open position by pivoting in a direction that is substantially perpendicular to a longitudinal axis of the peristaltic tube such that the release catch is configured to grip a latching surface of the latching receiver, wherein in the closed position the free-flow prevention arm and the frame compressively occlude the peristaltic tube, and in the open position the free-flow prevention arm and the frame allow the peristaltic tube to pass therebetween such that the peristaltic tube is not occluded; and
a biasing mechanism located between the frame and the free-flow prevention arm, the biasing mechanism configured to bias the free-flow prevention arm to the closed position.
