A tubing clamp controlling flow within compressible tubing passing through the clamp which is adapted for inserting the tubing sidewise into the clamp upon opening of a hinged side wall. An adjustable flow controller overlies the tubing and is adapted to rotate, bear upon and squeeze the tubing for precise flow control. A lever arm to actuate the flow controller is in ratcheting engagement with an arcuate bar to hold the lever arm and cylindrical surface of the flow controller in the desired rotative position. The selected position of the lever arm can then be recorded. The tubing clamp can be constructed as a one-piece structure by use of a single mold and prepared as a kit to facilitate use for medical purposes. The assembly of the clamp is thus simplified and the method for controlling flow is accomplished by a series of simple steps.
