A snap fit interlock for attaching a component of a luggage article may include a snap fitting connecting a luggage article component to a luggage shell, and a locking feature automatically limiting the disengagement of the snap fitting once the snap fitting is engaged. The snap fitting may engage and move the locking feature as the snap fitting is moved in an insertion direction during attachment of the luggage article component to the luggage shell. The locking feature may disengage from the snap fitting when the snap fitting engages the luggage shell. A portion of the locking feature may be automatically positioned between the snap fitting and the luggage article component to limit disconnection of the snap fitting once engaged.
