ABSTRACT OF THE DISCLOSURE A separable integral donor connector with an improved clamping mechanism for use with flexible blood collection tubing is disclosed. The device is positioned in line with the blood tubing between a phlebotomy needle and the col- lection bag. Separation of the device is accomplished by manipulation and breaking of a thin frangible ring area and drawing the sections of the device apart. This separation exposes an internally-mounted needle that may be used for penetration of sample collection tube ciosures and subsequent collection of blood samples, The present embodiment of this invention includes improved manually-operated clamping means that are flexibly biased away from the blood tubing. Clamp- ing jaws of differing lengths are disclosed which, when engaged. overlap and cause an area of tubing to be collapsed into a distinctive, S-shaped configuration which crimps and more effectively seals the tubing against blood flow. The clamping device is free from restraints permitting sample, one-handed operation, as well as the broadest control over the blood flow.
