The invention relates to a suspension device for pneumatic gripping appliances, in particular suction cups, for gripping and handling parts, items and the like. It comprises a fixed supporting body (11), a tubular rod (12) movable axially in said body, and a return spring (13) between said body and said rod. This tubular rod (12) is guided on the supporting body (11) by the interposition of a slide jacket (20) in combination with the seals (16, 19) provided to prevent the air entering from outside when a suction/depression appliance is connected to the supporting body to activate the pneumatic gripping device.
