FASTENING DEVICE Abstract of the Disclosure A molded plastic female fastener component including an aperture having an entrance end for receiving a threaded stud or bolt. Within the aperture are retaining means in the form of an axially spaced series of flexible legs each of which extends about at least a portion of the inner circumference of the aperture to generally define a helical thread form. The legs have a cross-section which tapers from a relatively thick base to a thin outer end inclined in a direction away from the entrance of the aperture. The spacing between adjacent legs in the series is equal to the pitch of the threads of the associated stud. The resilient nature of the shape of the legs allows them to deflect over the threads during an axial "push-on" engagement but to latch under the threads to prevent axial disconnection except by an unthreading operation.
