Abstract
A quick connect coupling for high pressure fluid includes a male fitting body connected on the end of an elongated tube. The male fitting body has an annular recess for receiving a retainer movable between a compressed position allowing longitudinal insertion of the male fitting body within a corresponding female aperture and a released position for retaining the male fitting body seated within the female aperture. A visual indication is provided to signal if the retainer is fully seated within a corresponding groove of the female aperture. A locking member maintains the retainer in the released position in response to seating the male fitting body within the corresponding female aperture. A biasing member urges the male fitting body in an opposite direction with respect to the longitudinal insertion direction within the corresponding female aperture. A pop top releasibly engages with the male fitting body for holding the retainer in the compressed position until the male fitting body is seated within the corresponding female aperture.
