Abstract
An autoinjector having a body to receive a reservoir and an actuator sleeve including a contact end and extending inside the body and movable relative to the body between projecting positions and an actuated position. The actuator sleeve is in a first projecting position before actuation of the autoinjector and in a second projecting position after actuation. The actuator sleeve, in the second projecting position, extends axially further out from the body than in the first projecting position and includes an annular zone that, in the first projecting position, is arranged inside the body and in the second projecting position is arranged outside the body. The annular zone includes a visual indicator that the autoinjector has been actuated. Axially adjacent the annular zone the actuator sleeve includes a shoulder, projecting radially outwards relative to the visual indicator, thereby protecting the indicator against contact with the inside of the body.
