Claims

[Scope of utility model registration request]

A connecting joint for connecting tubes A and A' whose outer circumferential surfaces are formed in a spiral concave-convex wave shape, where the joint B is a cylindrical integral piece and the spiral concave-convex waveform of the connecting tubes A and A' is connected. The inner circumferential surface has a spiral corrugated waveform 2 which is screwed together with a predetermined gap s, and from the inner peripheral surface of the spiral corrugated waveform 2, the outer circumference of the spiral corrugated waveform 11 of the connected pipe bodies A and A' is connected. A spiral rib strip 4 whose diameter and the diameter of the tip portion 4' are approximately the same diameter or a slightly smaller diameter is integrally formed to protrude and is formed on the peripheral wall 1 at a substantially symmetrical position spaced apart from the axially intermediate portion by a predetermined distance. A helical tube connection joint having a structure having filler injection ports 3 and 3, respectively.
