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').

This invention relates to a cryogenic transfer hose for hydrocarbons comprising an inner hose, an outer hose arranged around the inner hose in a concentric manner and a spacer member bridging an annular gap between the inner and outer hoses, a fibrous insulation material forming a three dimensional matrix of fibres being comprised in the annular gap, characterised in that the outer hose comprises an elastomeric and/or a plastic material, the fibrous material being contiguous overall best a part of the length of the hoses with the inner and outer hose and forming a spacer member.

For connecting a connecting piece (10), for example a tube coupling or an armature or a fitting, to a heat insulated conduit pipe (1), a calibration ring (9) of the connecting piece is driven between the inner pipe (2) of the conduit pipe and the insulating layer (3) thereof. Subsequently, a shell (11) is fastened in the inner pipe, for example by pressing the shell into the inner pipe. Thus, the removal of the insulating layer (3) and the shell (4) of the conduit pipe is not necessary.
