Abstract
A connector assembly may be formed by the combination of a latch member and a connector member. The latch member has an annular collar and an arcuate latch wall extending from a circumferential edge of the annular collar. A latch recess and a latch arm are defined within the latch wall. A wing grip extends from an exterior surface of the latch wall adjacent the latch recess and is configured to reinforce the latch arm by countering a tendency of the latch arm to flex radially outward when the connector assembly is subject to a tension load along a longitudinal axis of the connector assembly. A plurality of snap arms are arranged about a circumference of the interior surface of the annular collar to engage the connector member. The connector member receives and retains the latch member directly about an outer male insertion surface thereof rather than passing a barbed end of the connector member through the latch member. The latch member and the connector member are correspondingly configured to freely rotate relative to one another upon assembly. An annular protrusion on an outer wall of the connector member acts as a tube stop.
