Abstract: This invention concerns a pneumatically controlled grasping device to grasp and handle items or bodies provided with a graspable member. It comprises a supporting sleeve (16, 36) that internally delimits an intermediate space (23, 43) contiguous to a distal opening and a guide chamber (23?, 43?) connected to a source of fluid under pressure. In the intermediate space a gripper means (21, 41) is mounted, facing the distal opening and designed to engage with the graspable member. In the guide chamber a control piston (22, 42) is housed movable into a first position which corresponds to an activation or deactivation of the gripper means by the fluid under pressure, and to a second position which corresponds to the deactivation or activation of said gripper means, by at least a flexible reaction element (27, 47). The gripper means can be equipped to grasp the graspable member from the outside or from inside when it has a cavity.
