An interlock, latching and retaining mechanism for use in an infusion system, embodying a latch arm mounted to a rotatable shaft having a plurality of cams and gears attached thereto, a rectangular faceplate with a plurality of apertures formed therethrough, and a clamp. Rotating the latch arm functions to engage fluid monitoring, flow control and pumping structure of the infusion system with a pumping segment for control of fluid flow through the segment and also causes the clamp to hold the pumping segment in a required position. In another aspect, rotation of the latch arm additionally causes an air-in-line sensor to rotate into position on the pumping segment.
