Abstract: An access port for a medical fluid container is provided and in one embodiment includes: (i) a shell; (ii) a perforator located within the shell, the perforator including an end configured to pierce a medical fluid container; and (iii) a safety tab connected to the perforator, the safety tab initially preventing the perforator from piercing the medical fluid container, the safety tab manually removable to enable the perforator to pierce the medical fluid container. The shell can include a pair of hingedly moving arms and members connected hingedly to the arms, the members operable to push the perforator towards the medical fluid container when the arms are pushed. The safety tab can include a plurality of frangible fixtures, the fixtures collectively providing a suitably high tamper resistance force, the fixtures individually providing a suitably low tab removal force.
