Abstract
A high pressure quick connector is disclosed for use in connecting brake lines of a vehicle, particularly to a brake junction for an anti-lock brake system. The connector includes a housing for receiving a tube retainer. The tube retainer has a lower cylindrical portion that is positively attached to enclose a flared end form to provide a fluid seal. Retaining means in the form of a snap ring works in conjunction with a pop top to provide a low force and a positive insertion indicator. The snap ring has ears that are compressed together and inserted up inside a slot in the pop top. Upon installation of the tube retainer and retaining means into a central bore of the housing, an end portion of the housing makes contact with the pop top so that the pop top slides up the tube. As the pop top slides up the tube, the snap ring ears are released from the pop top slot. The snap ring expands upon release into a final latching position with the housing and tube retainer. The tube retainer, snap ring, pop top and seal are pre-assembled and protected by a transport cover prior to final assembly and installation in the end product.
