摘要： The invention relates to an auto-injector for administering a dose of a liquid medicament (M). A shroud is arranged at least partially inside a housing, the shroud slidable in longitudinal direction between at least a retracted position, in which a hollow injection needle is exposable and an advanced position, in which the needle is covered by the shroud, wherein the shroud is arranged to be locked in the retracted position prior to manual operation of an activation means and wherein the shroud is arranged to be pushed towards the advanced position by a syringe spring when a drive means has been released by the activation means. A protective needle shield is attachable to the needle in a manner to partially protrude beyond the proximal end of the shroud through the orifice with the needle in its advanced position, wherein a syringe carrier is arranged inside the shroud for holding a syringe, the syringe carrier slidable with respect to the shroud, wherein the syringe carrier comprises at least one resilient snap for locking it to the shroud in order to prevent relative axial motion, wherein the snap is arranged to be supportable from inside by the protective needle shield when attached to the needle in order to remain engaged with the shroud and wherein the snap is inwardly biased to disengage from the shroud without support from inside in a manner to automatically disengage upon removal of the protective needle shield thus allowing the syringe and needle to be retracted into the covered position under load of the syringe spring.
