Abstract

A control clamp for adjusting the flow rate of a liquid through a flexible hose, such as the hose of an infusion device is provided with a manually operable means for varying the flow cross section of the hose. The means comprises three clamping jaws (14,14',14") of circular sector shape, in section perpendicular to the longitudinal axis of the hose (10), the relative spacing between the clamping jaws being variable by moving them along radii (16,16',16") which intersect the longitudinal axis (20).
