A needle-free connector for accessing a patient's intravenous line includes a hollow body having a first end with a first opening, a second end with a second opening, and an inner wall defining a chamber. A hollow piston disposed in the chamber is axially collapsible to allow fluid to flow between the inner wall of the hollow body and the outer surface of the hollow piston. An inner surface of the hollow piston includes a fluted section having a radial array of axial slots. The fluted section has a first radial thickness configured to buckle in response to axial force applied to the hollow piston. The hollow piston further includes a retrograde-reducing stiffener. The retrograde-reducing stiffener has a second radial thickness that is greater than the first radial thickness.
