A coupler for mounting to externally threaded reinforcing bar for use in concrete construction, the comprising a body having a portion with an internal thread for engagement with the thread of the reinforcing bar, wherein the thread form at the inner end portion of the internal thread includes on one of its flanks an enlargement of progressively increasing extension, the enlargement extending towards an opposing flank of the thread to provide an increasing friction fit with the thread of the bar. Various embodiments provide the enlargement being only on a part of the face of the flank whereby the remainder of the face of the flank forms, in conjunction with the adjacent flank of the bar thread during tightening, a void for receiving material displaced during tightening.
