Abstract: A syringe that includes an adapter section and a barrel having a chamber that holds a fluid. The adapter section includes outer and inner walls that form a first groove. The inner wall includes barrel threads and the outer wall includes a first projection. A cap having cap threads engages the barrel threads to removably attach the cap to the adapter section. A locking element having a sidewall that includes a second projection is received in the first groove and removably attached to the cap by an interference fit. Rotation of the cap causes upward movement of the cap that overcomes the interference fit thereby removing the cap. The locking element is prevented from being removed from the first groove due to contact between the first and second projections. Presence of the locking element in the first groove after the cap is removed provides evidence of tampering.
