Sealing connector with variable geometry

A variable geometry sealed coupling including two hollow elements (2, 3) each having a respective truncated face (22, 23) which is inclined by an angle ∝ with respect to a central axis (23, 33) of each element so that said central axes meet at a single point of intersection (C) at a center of the coupling, sealing and fixing means for coupling the hollow elements (2, 3) together in a sealed relationship with respect to one another while permitting the two hollow elements to be pivoted relative to one another to thereby change an angular relationship therebetween without changing a cross sectional dimension of a flow path through the two hollow elements;
