Abstract

Bind of unión between tubes, composed of a sleeve internally threaded by one of its ends and provided at its other inner end of a beveled edge of decreasing diameter towards the outside, characterized fundamentally because it comprises inside a first washer arranged next to the edge beveling of the sleeve, constituted by an open metallic ring, with its internal surface in the shape of a saw tooth, and of profile that adapts to said bevelled end; by a second washer with flat faces, in contact with said open ring, this second washer being in turn arranged in contact with an O-ring and a third washer comprising perimetric anchoring nails to the internal thread of the sleeve; fins that limit the penetration of one of the tubes to be joined, and an inclined edge of contact with the aforementioned O-ring, so that the connection between the tubes is made by inserting a first tube inside the fitting by its bevelled end, until that said tube makes butt with the fins arranged in the third washer, the second pipe to be joined by the other end of the coupling, causing the threading of this second tube a compression of the O-ring, thanks to the inclined face of the third washer, directs its mass against the periphery of the first tube, to the voice that causes a pressure on the open ring which causes its diameter decrease with the consequent interlocking of the saw tooth on the first tube, which is thus held.
