A drug delivery device comprising:
- a housing configured to receive a needle;
- and
- a cap removably attached to the housing to cover the needle;
- wherein the cap comprises a locking member having a proximal end and a distal end, the locking member connected to the cap at the distal end of the locking member and extending proximally from a wall of the cap, the locking member comprising a resiliently biased member that is held in a deflected position when the cap is fully connected to the drug delivery device, and wherein the locking member is movable relative to the wall of the cap to a locking position when the cap is removed from the housing, the locking member in the locking position being configured to prevent the cap from being attached to the housing.
