A no leak single use syringe has a needle (26) which retracts into the plunger (15) after use, and when the needle (26) is retracted, the syringe is sealed to prevent any liquid still on or in the needle from leaking from the syringe. A pierceable seal (17) across the front of the plunger (15) is self-sealing to prevent any liquid leaking from the front of the syringe, and the distal end (67) of the plunger seals against the rear of the barrel (71) of the syringe to prevent leakage from the rear.
