A marker for fire hydrants and other underground utilities fixtures consists of an elongated tube of brightly coloured resilient plastics material. It is mounted, for example, on the bottom flange of a fire hydrant by a flat metal bar bolted to the flange and carrying an upright stud that fits into the bottom end of the tube. The stud carries annular ribs with a diameter slightly greater than the inside diameter of the tube so that the tube is not readily removed from the bracket.
