A heat shield assembly for a fuel nozzle of a gas turbine engine thermally isolates the heat shield from the fuel nozzle. The heat shield assembly includes a pair of U-shaped heat shield members secured together to form an enclosure for the fuel nozzle, and at least one clip member which secures the heat shield members to the fuel nozzle at about the midpoint of the fuel nozzle stem. The clip member includes a base which is attached to the stem of the fuel nozzle such as by brazing or welding. The clip member also includes at least one, and preferably two, outwardly-extending flexible connector arms which are attached to the heat shield members. The arms are preferably attached to the heat shield such as by welding the arms into the seams of the heat shield members when the heat shield members are initially secured together. The open upper end of the heat shield is sized so as to tightly receive an enlarged neck of the fuel nozzle to prevent combustion gasses from flowing between the heat shield members and the fuel nozzle.
