A problem solved by this invention is to enable prevention of damage to a connector in a fluid transfer tube that is made by mounting a connector to an end of a tube, even when an outside air temperature falls below freezing point. The problem is solved as follows. In a fluid transfer tube that is made by mounting pipe joints (4 and 4') to ends of a tube (1) that has elasticity, tube connecting portions (3 and 3') of the pipe joints (4 and 4') and sections of the tube (1) in the vicinity of the tube connecting portions (3 and 3') are covered with heat radiation preventing covers (9 and 9') to thereby delay freezing of a fluid inside the tube (1) sections that are covered by the heat radiation preventing covers (9 and 9').
