A flow control device includes a first member and a second member which has a movable portion. The first member accommodates the attachment of a length of flexible conduit. The second member can be positioned on the first member to sandwich the secured conduit between the first member and the movable portion of the second member. When in this position, displacement of the movable portion serves to selectively pinch close the secured conduit between the movable portion and the first member. Fluid flow through the conduit can thus be conveniently controlled. The device is extremely adaptable and can be readily incorporated into virtually any fluid system which requires complex, repetitive valving functions, such as those associated with a plasmapheresis assembly.
