A needle assembly (10； 210) for a prefilled injection syringe is described. Aneedle holder (12； 212) has a needle (14； 214) secured to it and is adapted to besecured to a syringe barrel of the injection syringe. A needle sheath (16； 216)has a distal end forming a releasable sterile seal with the needle holder (12；212), and surrounds and shields the needle (14； 214) . A needle seal (18； 218) surmountsthe needle tip and is arranged at least in part in the proximal end of the needlesheath (16； 216) and closed off by a closure element (20； 220) . A closure connectionbetween the closure element (20； 220) and the needle sheath (16； 216) is configuredas a non-releasable and sterile barrier (54； 254) produced by means of bondingor welding.
