A zipper profile for a fastener assembly is provided. The profile includes a male element (106) and a female element (100). The female element has a pair of jaws (101, 121) that are movable with respect to one another about a common fulcrum region (102) and a pair of arms (103, 123), each of which are coupled to a corresponding one of the pair of jaws at the fulcrum region. Each of the arms has an end (104, 105) opposite from the fulcrum region that is shaped for engagement with a slider (208), and the jaws have an open position and a closed position. The arms are disposed to cause movement of the jaws between the closed position and the open position when the arms experience displacement about the fulcrum region. Displacement about the fulcrum region may be effectuated by motion of a slider relative to the arms. The male element is captured by the female element when the jaws are in the closed position and released when the jaws are in the open position.
