Abstract

An end-to-end joint for joining end zones (2, 3) of body ducts comprises: a first joining member (4) and a second joining member (5) that can be associated with corresponding end zones (2, 3) of the duct to be joined and a connector (6) that can be associated with the two joining member (4, 5) in order to connect them to each other; each of the two joining members (4, 5) comprises a first ring (7) equipped with a plurality of rods (8) positioned along the ring's directrices; a second ring (9) coaxial with the first ring (7) and having a diameter (D9) not greater than the diameter (D7) of the first ring (7); arms (10) each having a first end (10a) connected to the first ring (7) and a second end (10b) connected to the second ring (9) to position the rings (7, 9) at a predetermined axial distance, with the rods (8) of the first ring (7) projecting towards the second ring (9); the arms (10) are plastically deformable from an open position where the rings (7, 9) are at said predetermined axial distance, to a bent position where the rings (7, 9) are close together and the rods (8) are positioned inside the second ring (9) interacting with the rods (8) to bend them in such a way that they converge towards an axis (X) of the rings (7, 9) in order to penetrate a wall of the duct (2, 3).
