A tensioning device for use with a flexible cover on an open top receptacle such as a dump truck maintains the cover in a taut position and minimizes billowing of the cover during deployment, refurling, or transit. Spring biased arms attached to a tensioning bar urge said cover towards the top edge of said receptacle, keeping the tensioned cover proximate to the top edge of the receptacle sides. The open top of the receptacle is thereby closed during transit as the cover remains in substantial communication with the top edge of the receptacle and therefore resistant to billowing and wind agitation.
