Abstract: A vacuum—actuated handling device including, in the inner space (12) of a hollow body (11) with closed ends, a guide cylinder (13) defining an axial chamber (26) and, with the inner space, an annular compartment (25). In the chamber (26) a piston (14) movable between a rearward position adjacent to a first end and a forward position adjacent to a second end of said body (11) is accommodated. The piston is provided with an axially pierced rod (15), emerging from the second end of the body, carrying a gripping end sucker (27) and it is connected to a return spring (23) aiming to move the piston (14) to the rearward position. The piston (14) divides the chamber (26) in a first part of the chamber (a) adjacent to the first end and a second part of the chamber (b) on the side of said piston rod (15).
