A needle holder for use with a fluid transfer system of the type having a standard threaded cannula and a fluid container. The needle holder includes an actuation mechanism for detachably mounting a cannula to the holder, the actuation mechanism including pivotable threaded halves and an actuator operably associated therewith. In a cannula-mounting position, facing surfaces on the threaded halves cooperate to define a threaded passageway for engaging the cannula. Upon operation of the actuator, the threaded halves pivot to a retracted position to disengage from the cannula. |
