The injection and pressure body has a filling tube (1) as a woven stocking, with one or more reinforcement wires and/or tubes and/or rods and/or distorted plate strips (2) between the woven stockings (1,4). An outer closed woven stocking (4) is along the axis of the injection body, round its inner stocking (1) with an open end. The reinforcements (2) are round the inner stocking (1), bonded to its woven fabric, to fix them in place after the body has been filled or pressed. The stockings are at least partially of a stretch metal mesh.
