Abstract: The present invention is a quick connector preferably for use in connecting a fuel filler neck to a fuel tank. The connector includes a housing having a first end which receives a tube or nipple having an upset portion which is preferably mounted to the fuel tank. The connector includes a sliding collar with expandable fingers, a compression ring mounted about the collar and retaining forks for retaining the collar and ring within the housing. The upset can be inserted past the expandable fingers with little force. When the tube is attempted to be withdrawn, the compression ring compresses the fingers about the tube restricting release requiring exceedingly larger forces to remove the tube. The opposite end of the connector of the disclosed embodiment includes a quick connect for connecting a hose to the housing. This connector includes a compression sleeve which is mounted about the hose and compressed by a locking ring which locks to the housing.

Abstract: A synthetic with an opening at the top and a concave spherical surface extending from the opening, where a ball head of a ball stud is fixed, has a circular concave step on the outer surface of the housing surround the opening. A metal ring is fixed on the circular step so that the strength of the opening of the synthetic resin housing in a radial inward direction is greatly increased to resist the pull-out load on the ball stud. Warping of the opening is thereby prevented.
