A safety assembly includes a holder with a proximal end, a distal end and a tubular sidewall extending between the ends. The proximal end is configured to engage a needle assembly. The distal end is configured to slidably receive a fluid collection tube. A shield is hingedly mounted to the distal end of the holder and can rotate from a first position where the shield lies adjacent the holder to a second position where the needle is shielded. A spring is disposed for biasing the shield to the second position. A latch is disposed on the holder for movement between a locking position where the latch holds the shield in the first position and a release position where the latch permits the shield to be propelled to the second position.
