A connector intended to function as a tread-linking means for a duckboard of the kind in question, wherein the connector comprises: an end region (13, 14) adapted to couple with one of a successive adjacent pair of treads of the duckboard; an opposite end region (13, 14) adapted either to couple with the other of said successive adjacent pair of treads; or integral with said other of said successive adjacent pair of treads and characterised by a region (12) which is more flexible than an adjacent region and which enables the connector to hinge.
