A tube and tube shield assembly comprises a cylindrical tube having a lug extending radially therefrom and a tube shield. The tube shield includes a semi-cylindrical shield member having a diameter substantially equal to that of the tube, the shield member having a slot formed therein for receiving the lug, and a retainer for retaining the shield member in engagement around the tube. The tube shield has an upper end and a lower end, and the slot is formed either extending inwardly of the lower end, for use with vertically-oriented tubes, or the tube shield has the slot formed intermediate its ends, for use with horizontally-oriented tubes. The retainer can comprise at least two U-shaped straps, each of the straps having opposed ends attached, for example by welding, to the tube shield.
