  • Secondary retention clip with pivoting clamping jaws
    Patent number: 5209529
    Abstract: A secondary retention clip to prevent the complete separation of the female end of an air conditioning hose from a connected male end. The female end is flared and the male end has a coupling flange which receives the flared female end. The clip has a box like receptacle for the coupling flange. The connected tubes are located in side openings which communicate with a open top. Stops prevent entry of the flared portion so that the clip will be attached with the parts properly connected. Clamping jaws secure the hose in position and prevent its vibration.
