A pre-filled syringe-needle assembly in which the needle is covered with a shield-closure unit to assure sterility. Said shield-closure unit comprises a tube which covers the needle and a plug for said tube, one end of said tube being adapted for fitting tightly over the reduced part of the barrel of a syringe, and the other end being covered by the plug, both said end and plug covering it being adapted to provide an air-tight fit between them, said plug being sufficiently long to engage the tip of the needle inside the tube.
