Abstract
A locking quick connect assembly is provided for removably coupling a first tube and a second tube. A quick connect housing presents a central bore for receiving the second tube. A redundant latch component positionable between an unlocked position and a locked position may be provided to slidingly engage the quick connect housing. A twist lock retainer surrounds the quick connect housing and the redundant latch component. The redundant latch component includes an axially extending redundant latch retaining arm and the twist lock retainer includes a locking channel for receiving the redundant latch retaining arm. The twist lock retainer also includes a twist lock retaining arm that locks against a bead of the second tube to resists separation. The twist lock retaining arm extends perpendicularly to and radially inwardly of the locking channel to interleavingly engage the redundant latch retaining arm thus preventing unwanted decoupling of the assembly.
