Abstract: A tool for the connection of tubes (T) by means of connection sleeves (C), comprising two jaws (2, 3) which are mutually movable between an open rest position, and a closed work position wherein they define an annular reception seat (7) of the connection sleeve (C), and wherein they turn a circumferential series of radial punches (6) towards the sleeve (C); said jaws (2, 3) each comprising at least one punch (6) sliding towards the center of said reception seat (7), and being mutually connected by means of a kinematic system which permits them, when they are found in said open rest position, to confer a generally open-ring shape to said reception seat (7), through whose lateral opening (8) the connection sleeve (C) can be inserted and extracted by lateral movement.
