The cap comprises gripping means reversibly operatable between a first condition in which there is no gripping engagement between the mounted cap portion and the needle cap, this allowing the cap portion to be removed from the main portion without removing the needle cap from the hub, and a second condition in which the cap portion grippingly can engage the needle cap of a needle assembly, this allowing the needle cap to be removed from the hub together with the cap. The cap further comprises user actuation means for operating the gripping means between the two conditions.
