There is provided an auto-injector (1) for a syringe that is suitable for use in the injected delivery of drug to a patient. The auto-injector comprises a housing defining a housing cavity arranged for receipt of a syringe; a needle cover (70) defining a needle sheath (76) arranged in a rest configuration for sealing of a needle tip of the syringe; and provided to the housing, one or more (e.g. resiliently) flexible elements (80) extending into the housing cavity thereof. In the rest configuration, the one or more (e.g. resiliently) flexible elements contact the needle cover to restrict movement thereof. In a use configuration the needle cover is removed from the needle tip such that the one or more (e.g. resiliently) flexible elements flex into the housing cavity to provide a barrier surface for obstructing exit of the syringe barrel therefrom. |
