A fluid connection joint to couple tubular pipes intended to convey gas, compressed air and other fluids. The fluid connection joint includes a deformable internal ring having sealing surfaces internally to engage with an outer surface of a first tubular element and frontally to engage with a second tubular element. The deformable internal ring is located within a housing that is coupled to a flange of the second tubular element by fixing screws. The tightening of the fixing screws results in a substantially radial compression of the internal ring and seals around the first tubular element and a second substantially axial compression of the frontal seal against the flange.
