a cap body configured to be detachably mounted to a housing of the medicament delivery device; and
a cap lid configured to be attached to the cap body;
wherein the cap body and the cap lid are two separate components configured to be located in ready-to-use positions on a distal end of the medicament delivery device separately,
wherein the cap body is configured to receive a needle sleeve of the medicament delivery device through a proximal end of the cap body and the cap lid at a distal end of the cap body when the cap assembly is attached to the medicament delivery device in the ready-to-use position of the cap body,
wherein the cap lid comprises an anti-recapping element configured to prevent the cap assembly from being reattached to the housing of the medicament delivery device once the cap assembly has been removed and the medicament delivery device has been used,
wherein the anti-recapping element comprises a projection extending in a proximal direction and is configured to contact and engage the needle sleeve of the medicament delivery device to prevent the cap assembly being fully reattached to the housing of the medicament delivery device upon attempted recapping once the medicament delivery device has been used.
