ABSTRACT:
A clamping device for controlling liquid flow in a length of flexible tubing; the device includes a generally planar support having a keyhole, an annular flexible sleeve seated in the keyhole for receiving the tubing in an orientation generally perpendicular to the planar support, and a mechanism for moving the flexible sleeve between the larger side of the keyhole and the smaller side of the keyhole to cause pinching of the tubing to control liquid flow.
