A combination stopper and shield closure for sealing the open end of an evacuated body fluid collection tube. The stopper is headless and includes a well in its top surface with an undercut at its base. The shield includes a plurality of flexible fingers extending from its top surface, each finger including a cleat at its proximal end for engaging with the undercut in the stopper. The interaction between the cleats and the undercut serve to securely hold the stopper within the shield and eliminate compression forces being applied to the stopper by the shield. In addition, the base of the well is convex to direct any residue body fluid away from the center of the well towards the undercut and minimize residue build-up, and the bottom portion of the stopper is concave to reduce the thickness of the stopper's diaphragm and reduce penetration force.
