An elongated tubular member having open ends with radial end faces surrounding the respective open ends. A corrosion-resistant and protective plug member having a flange portion is received in each of the open ends with the flange portion overlying the respective radial end face. An insulating jacket surrounds the tubular member and has its end portions formed into radially inwardly extending circumferential beads which abut against and are sealed to the respective flange portions of the plug members so as to fixedly secure the latter in the open ends.
