An injection device comprising a support stock that supports a syringe having a plunger and a needle. The plunger is movable in an axial direction to force liquid from the syringe through the needle. A safety valve prevents flow of liquid from the syringe to the needle. A stabilizing sight is provided, for application against skin during an injection. The stabilizing sight is mounted on the device for movement relative to the device such that when the device is pressed against the skin the needle moves from a retracted position relative to the stabilizing sight to an advanced position relative to the stabilizing sight to penetrate the skin. The stabilizing sight is interconnected with the safety valve in such a way that when the needle is in that advanced position the safety valve is moved to an open position and when the needle is in that retracted position the safety valve is in a closed position.
