<p>The manifold includes a sleeve element (10) extending longitudinally about an axis (x), formed in one piece of plastics material and having a plurality of pairs of apertures (11, 12) distributed along the manifold. The apertures of each pair are aligned transversely with each other for engaging and locking on the manifold respective pairs of tubular metal elements (20, 30) operable to be connected mechanically the one to the other (16) and to a branch (T) of the heating system. <IMAGE></p> |
