A needle assembly () for a prefilled injection syringe is described. A needle holder () has a needle () secured to it and is adapted to be secured to a syringe barrel of the injection syringe. A needle sheath () has a distal end forming a releasable sterile seal with the needle holder (), and surrounds and shields the needle (). A needle seal () surmounts the needle tip and is arranged at least in part in the proximal end of the needle sheath () and closed off by a closure element (). A closure connection between the closure element () and the needle sheath () is configured as a non-releasable and sterile barrier () produced by means of bonding or welding. 110210.
