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.

Abstract: Activation and locking device for opening and closing a sun roof for a motor vehicle which includes a tow-sliding carriage (24) coupled to an entraining body (111) through grooved side levers (28) wherein fulcrum pins (26) of round sector lever (13) provided with a toothed round sector (14) engage. The lever (13) and said entraining body (111) are coupled to a shaped lever (5) for the hooking and support of the sliding glass or cove ring (1) of the sun roof. The assembly of carriage (24), entraining body (111) and shaped lever (5) slides in guides provided in guide section (20). The carriages (24) are provided with front side arms (122) having longitudinal eyelets (132) wherein engage the side sliding slides (115) of the entraining body (111), the through pins (118) provided at the front ends (117) of shaped lever (5) and pins (160) of lock-teeth (161).

Abstract: A worm screw (1), controlled in rotation by a knob (2) or a reduction gear, is coupled to two helical gears (3) to which are stiffly connected primary levers (6) or (6'), which, through end supports (9), form an articulated pantograph structure with an equal number of secondary levers (10) or (10') whose ends are linked to pins (12) fixed on the roofs (13) of vehicles.
