An autoinjector device is disclosed which comprises a body portion and a syringe carrier, for supporting a syringe with a needle at its forward end. The syringe carrier is moveably mounted within the housing such that forward movement relative to the housing may extend the needle from a forward end of the body. The syringe carrier has a latch element arranged to cooperate with a corresponding retention feature of the body portion to releasably hold the syringe carrier in a rearward position within the body potion. A delivery mechanism is arranged to forwardly displace the syringe carrier relative to the housing and to deliver a dose of medicament from the syringe. A shroud assembly is provided at a forward end of the device. The shroud further comprises a locking arrangement which blocks releasing movement of the latch element from the retention feature when the shroud is in a first, forward position and is unlocked when the shroud is in a second, rearward position.
