1. A syringe adapter comprising:
a housing having a first end and a second end, the first end configured to be secured to a first container;
a cannula having a first end and a second end, the second end of the cannula positioned within the housing; and
a collet having a first end and a second end, at least a portion of the collet received within the housing, the collet comprising a body defining a passageway, a membrane received by the passageway, and a locking member connected to the body of the collet, the membrane comprising a body having a first end and a second end, at least a portion of the body of the membrane engaging the body of the collet, the body of the membrane defining a passageway extending from the first end of the membrane body towards the second end of the membrane body and terminating intermediate the first and second ends of the membrane body, the collet movable from a first position where the locking member is open to receive a mating connector to a second position where radially outward movement of the locking member is restricted,
wherein when the collet is in the first position the second end of the cannula is positioned within the membrane passageway,
wherein, during movement of the collet from the first position to the second position, the membrane is axially fixed to the collet relative to the locking member and the membrane slides relative to the cannula, and
wherein, in the second position of the collet, the second end of the membrane body is pierced by the cannula and the collet is rotatable relative to the housing about a longitudinal axis of the housing.
