A rigid needle shield (10) for covering a distal end of a syringe is provided. The rigid needle shield includes an elongated flexible member (20) connected to a sidewall of the rigid needle shield for moving the rigid needle shield between a first relaxed position and a second flexed position. When in the first relaxed position, the elongated flexible member is substantially within the rigid needle shield. However, when the elongated flexible member is moved to the second flexed position, the elongated flexible member extends beyond a proximal end of the rigid needle shield to engage a needle hub or a shoulder of the syringe to move the rigid needle shield distally relative to the syringe.
