A thermal insulation device of a screwed junction between two sections of pipe constituted by an outer pipe surrounding an inner pipe between which thermal insulation material is positioned, the inner pipes of each section being assembled together by said screwed junction, one section delimiting a male portion and the other section delimiting a female portion, the two portions being fitted into one another in order to delimit said screwed junction, wherein the male portion is constituted by the inner pipe and a tubular part connected to the inner pipe, the diameter of said tubular part being less than that of the outer pipe, said male portion incorporates an insulating material, and wherein the female portion is constituted by a part of the outer pipe and an intermediate tubular part connecting the inner pipe to the outer pipe, the inner diameter of said intermediate part being greater that the outer diameter of the tubular part of the male portion, a thermally insulating material being inserted between the part of the external pipe and the intermediary part.
