An injection device comprising a housing 10, 20 for receiving a syringe 22 comprising a needle and protective sheath covering the needle, a carriage 11 located within the housing and facilitating movement of the syringe between a retracted position and an injection position in which the needle projects through an opening in the housing, and a sheath remover 13 attached to the housing and configured to capture the protective sheath upon loading of a syringe into the housing and to remove the protective sheath upon detachment from the housing, thereby exposing the needle. The device is configured such that a distal end of the sheath remover 13 is in close proximity with a proximal end of the syringe carriage 11 so as to substantially block movement of the carriage towards the opening whilst the sheath remover is connected to the housing. The needle sheath may comprise snap-in fingers 14 which engage behind the needle sheath, leaving only a small gap G between the syringe carrier 11 and the snap-in fingers 14. |
