Abstract
The invention is an improved fluid transport conduit coupling having a substantially tubular stem defining a central bore terminating at each end in first and second perimeter openings, a conduit insert including a body member having opposing first and second portions and adapted to receive said stem, and latching means for limiting axial movement between the stem and the conduit insert upon sealing engagement of the stem and the conduit insert. The improvement includes a latch support means disposed on the stem and at least one disengagement slot proximate the first perimeter opening, and at least one radially deflectable locking beam extending substantially axially from the first portion of the body member conduit insert. The improvement also includes the support means being engageable with the locking beam to selectively limit axial movement of the conduit insert relative to the stem upon sealing engagement thereof, with the disengagement slot permitting relative disengagement of the locking beam with the support means. The improvement further includes seal means interposed between the stem and the conduit insert for preventing fluid flow therebetween.
