A pair of gripping frame members (11,12) are hingedly connected together at one end thereof. Cooperating rollers (16,17) are rotatably coupled to the gripping members (11,12) adjacent the hinge (13,14) therebetween. The rollers (16,17) are positioned adjacent one another whereby a uniform space is created between the parallel, aligned surfaces of the rollers (16,17) which are adapted to receive flexible fluid-filled tubing (15) connected to a blood donor bag. When the gripping frame members (11,12) are positioned adjacent one another, the aligned surfaces of the rollers (16,17) will fully compress the surfaces of the tubing (15). Opposed crimping heads (30,31) coupled to the gripping frame members (11,12) are adapted to crush a securing clip (34) disposed about the tubing (15) thereby sealing the fluid-filled tubing (15) when the heads (30,31) are positioned adjacent one another.
