Abstract: A guard assembly for a guy-wire connected to a ground anchor rod. The assembly includes at least one elongate generally tubular body of weather-and-impact-resistant, generally rigid plastic, having a 180.degree. arcuate portion and at each end thereof a straight extension portion, the extension portions being generally parallel to each other. Preferably, two such bodies are assembled together with the extension portions of one body touching and overlapping those of the other. The overlapping extension portions are diametrically opposite each other, and the two arcuate portions are diametrically opposite each other. This assembly encloses the guy-wire and/or its ground anchor rod, preferably from about ground level to a height well thereabove. Bolts extend diametrically across this assembly to hold it together, preferably from one pair of overlapping portions to the other or across the centers of the arcs. Each bolt preferably has a vandal-resistant nut threaded on it.
