A duct vane assembly has a rail for supporting a flow diverting vane perpendicularly therefrom. The rail has at least one upstanding tab for each vane which is adapted for insertion longitudinally into a slot defined by a lateral strap formed on the vane adjacent its end. A finger on the tab projects into an opening on the vane adjacent the strap to affirmatively retain the vane in connected relation to the rail.
