摘要：
A needle assembly (2) for a drug delivery device (1) comprises a needle seal (3), a needle retainer (4) and a needle (5). The needle retainer (4) secures the needle (5) against displacement with respect to said needle retainer (4) when a dose of drug is being delivered. The needle seal (3) is configured to push onto the needle retainer (4) after delivering the dose of the drug, thereby unlocking the needle (5) from the needle retainer (4).
