Abstract: An injection device is disposable, and is designed to have a reusable firing mechanism fitted to its rear end. A syringe carrier within the barrel of the device is initially locked in a position with the needle of the syringe retracted by a locking element inserted laterally through the barrel. This element also holds an axially movable connector to which the firing mechanism connects. The device is made operable by removal of the locking element, and after use a return spring ensures that neither the syringe carrier nor the connector assume positions where the locking element can be reinserted. An adaptor may be provided to facilitate preparing a syringe with a two-component dose, and for disposal after use the adaptor with an empty vial still attached can be fitted to the rear end of the injection device in place of the firing mechanism.
