1. A perforating connector assembly comprising:
a valve for sealing to a medical fluid container; and
a perforating connector comprising
a perforator sealingly accepted by the valve, the perforator including a spiked end and a lever, the lever including a tab,
a shell extending around the perforator sealingly accepted by the valve, the shell including a pre-activation opening and a post-activation opening,
a spring held compressed during pre-activation by the tab of the lever of the perforator being located within the pre-activation opening of the shell, and
an actuator slidingly engaged to the shell, the actuator including a projection, the actuator configured to be translated by a user so that the projection becomes aligned with the tab located within the pre-activation opening, wherein the user is then able to push the projection into the pre-activation opening to disengage the tab from the pre-activation opening, and wherein the spring is then able to decompress and translate the perforator so that the medical fluid container is pierced open by the spiked end and the tab becomes located within the post-activation opening.
