Improvements in the articulation joints of tubular elements, characterized in that the frame of the ball joint is U-section for fitting the solidary tube in the fixed tube of the joint. The two parallel flat surfaces of the branches of the U-section, constitute a rigid assembly because the edges of one side are extended according to overlapping faces, which close one face of the frame leaving open the part next to the area of connection of the pieces parallel to allow the passage of the fixed tube. The central areas of the planar surfaces of the frame have respective facing recesses. The straight main branch of the recess has a rounded end. The three rounded end branches of the recess correspond to three anchoring points of the movable tube of the joint, whereby three positions of inclination of various angular openings of one tube with respect to the other are defined.
