The wire fixing bracket, especially for attaching to a supporting post (P), consists of a strip of metal cut from 0.2 - 3 mm thick sheet, having a clip (1) at each end in the form of a spring-loaded tongue, lines of holes (5) to facilitate bending to the shape of a supporting post surface, and a hole for a fastening (4). When used with a wooden post the strip can be shaped to form spikes on its inner surface.
