Abstract: The present invention is a clip for securing the nipple of a fuel filter within a fuel line connector assembly housing provided on a fuel line in order to secure the fuel filter to the fuel line. The clip is provided with a horizontally oriented connecting segment having two ends. Each end of the connecting segment is provided with a leg that extends downward therefrom. The legs are spaced apart from each other so as to be insertable through openings provided in the connector assembly housing. Each of the legs is provided with a flipper, with the flipper of one leg being offset from the flipper of the other leg with respect to a horizontal center line of the nipple when the nipple is installed in the connector assembly housing. The flippers are oriented toward the opposing legs so that as the nipple is inserted into the connector assembly housing, the nipple is forced between the flippers and the legs, causing the legs to rotate and squeeze the nipple.
