Vehicular Interior Assembly

A vehicular interior assembly including an air duct defining a duct opening having at least one key receiver and a vent that includes a vent body defining a longitudinal axis and a vent opening axially therethrough. At least one key extends outward from the vent body substantially perpendicular to the longitudinal axis and is sized for receipt through the corresponding at least one key receiver. The vent body is axially receivable into the duct opening with the at least one key received through the corresponding at least one key receiver. Rotation of the vent body about its longitudinal axis moves the at least one key from an axial movable position to an axial non-movable position. A trim retention feature disposed on the vent body retains a vehicular trim component against the air duct while the at least one key is in its axial non-movable position.
