Decking clip

A decking clip, and method of use, for securing decking planks (60) to a joist (54), comprises a plate (68) adapted to be secured overlying the joist; first and second rigidly upstanding legs (62, 64) having spikes or tangs (56, 66) on their upper ends extending generally parallel to the plate and pointing in opposite directions; wherein the legs are spaced apart across the plate to enable one of the spikes to be driven into the edge of a plank (58) by one or more hammer blows without the hammer engaging the other leg or spike. The plate may have at least one aperture through which a fixing device (52), e.g. nail or screw, can be driven into the joist below. The clip is preferably either formed from a metal blank by bending appropriate regions to form the legs and spikes, or by casting or cold forming. A tool to assist in driving a spike of the decking clip into the edge of the plank and a spacer plate are also disclosed.
