Coupling device for tubular elements, essentially characterized by consisting of a core from which they derive, their axes forming angles in correspondence with the directions of the elements to be coupled, extensions of a truncated cone shape, ending in cylindrical and threaded lugs, conjugates of individual casings internally threaded trunnions and with its external surface provided with a plurality of oblique grooves with respect to the ideal axis, the assembly completing a tubular component with an outer diameter similar to the internal one of the tubes to be coupled, which presents in its ends rectilinear sizes oriented according to generatrices and lengths equivalent to approximately half that of the component, resulting in the binding effect of the forced expansion of the tubular component, made of a flexible and elastic material, inside one of the tubular elements to be joined, by effect of the end threading of the frustoconical wick and the cap internal of the device, as well as the housing of the wick itself in the head of the tubular component.
