Injection device

A method of removing a cap from an end of a body of an injection device, the cap comprising an outer cap and a needle shield to frictionally engage with a syringe, comprising the steps of:

• rotating the outer cap about a longitudinal axis of the body to move a lock of the injection device to a unlocked state, wherein the cap is held in place with the body against a force of a biasing member by the lock in a locked state prior to rotation of the outer cap, the lock comprising a latch or bayonet connection;
• and
• removing the cap from the end of the body, wherein the cap is urged away from the body by the force of the biasing member, and wherein the biasing force of the biasing member is configured to overcome friction between the cap and the body to separate the needle shield from the syringe in the unlocked state.
