    Patent number: 7448653
    Abstract: A female connector for releasable coupling with a male connector is disclosed herein. The male connector defines a fluid conduit and includes a male end adapted to be received within the female connector. The male end includes a coupling feature. The female connector comprises an opening, a collet finger, and an actuation element. The opening is adapted to guide the male connector along a first line of action as the male connector passes into the opening to be received within the female connector. The collet finger includes an engagement feature adapted to engage the coupling feature of the male end and displace along a second line of action generally normal to the first line of action. The actuation element is adapted to displace along a third line of action generally normal to the first and second lines of action in order to disengage the engagement feature from the coupling feature of the male end.
