Integrated junction system for tubular fluid distribution elements

Integrated junction system for tubular fluid distribution elements, comprising:

• a first tubular element which has, at a first end an enlarged cup shape with a base which determines the formation of an annular shoulder inside said first tubular element, the first tubular element having an external diameter,
• a ring with a shaped section, which is associated with a second end of said first tubular element, equipped with a shaped protrusion, which abuts on an edge of this second end and with a radial appendix which is associated with the second end of the first tubular element,
• wherein said system, in order to join two said tubular elements of the same structural configuration, provides that said second end of the first tubular element equipped with said ring is inserted into the first end of a second said tubular element having said enlarged cup shape until the protrusion of the ring of the first tubular element comes into contact with the annular shoulder formed inside the second said tubular element,
• wherein said radial appendix is conical in shape, able to facilitate insertion thereof into the second end of the first tubular element,
• the conical protrusion of the ring has an external diameter which always has a size greater than the external diameter of the first tubular element, so as provide a sealing fit with an inner surface of the enlarged cup shape of the first end and
• wherein the ring is configured to not extend around the outer surface of the first tubular element.
