ABSTRACT:
A plastic fastener assembly is provided which has a base with an upstanding stab which has a single first tooth formed on one side of the stab and at least one second tooth formed on the opposite side of the stab. A cover defines an opening for receiving the stab. The cover has a control rail adjacent the opening and a flap extending into the opening opposite the central rail. The rail slides along the surface of the first tooth during assembly and urges the first tooth and stab toward the flap until the rail engages the notch of the first tooth. The flap automatically moves from the base during assembly as the first tooth and stab move toward the flap. The flap engages the second tooth when assembled inhibiting separation of the stab and cover.
