A flow control device for flexible tubing wherein the device utilizes a toggle action in compressing the tubing against an anvil surface. A ratchet element is employed in conjunction with the toggle-action clamp to incrementally compress the tubing against the anvil surface. The clamp can be inexpensively molded in one piece and easily assembled without the placement of additional parts in the clamp body. The ratchet and toggle mechanisms offer the advantage of a one-hand operation for incremental compression of the tubing as well as a release of the clamp member.
