Abstract: A grip contains a profiled membrane (1) made of flexible material with two lips (1c) (1d) forming an interior collar, leaving the passage for the introduction of a tool shaft with any cross section free and which, when used and handled, allows the collars to fulfil the function of sealing lips and in that the profiled membrane forms at least one air chamber (1a) on the inside, and when the grip is handled by the user the membrane is deformed and creates a vacuum in the interior chambers (1a) (1b), forming suction pads on the tool shaft.

Abstract: Gripping device suitable for percussion tools of the type comprising a sleeve tube made of plastic that fits into the body of the tool, characterised in that it comprises a plastic sleeve tube (1) that is structurally flexible and comprises a plurality of large-diameter annular shapes (1.1) joined to each other by connecting shapes (1.2) of smaller cross-section to define a bellows structure with undulations, and in that, at the location of each ring, an internal circular projection (1.3) is provided that presses against the body of the tool, and in that the sleeve tube has at least one internal collar (1.4) capable of fitting and clipping inside at least one circular groove (2.1) formed on the body of the tool.
