An elongated drawbar tension element is provided for the conveyor chain of an en masse conveyor. The drawbar includes a hollow hub at one end for receiving an enlargement at the other end of an adjacent drawbar element coupled thereto to form a chain. The side faces of the hollow drawbar hub are formed with tapered dovetail shaped grooves for receiving complementary tapered dovetail shaped tongues formed on the inboard sides of transversely extending conveyor flights. The tapered tongue and groove connection is self-tightening in normal use and the complementary dovetail configuration thereof prevents lateral separation of the conveyor flights from the drawbar hub. An adhesive material may be applied to the self-tightening connection to prevent loosening thereof and separation of the flights from the drawbar elements when the conveyor chain is subjected to vibration, irregular loads or is moving in a downward direction.
