Abstract

The invention relates to a fluid-actuable releaser in which an annular piston (6) is guided in a casing (3) which is provided with a sleeve (10) for guiding the annular piston (6) radially internally and for sealing purposes, the sleeve (10) being axially fixed by partial plastic deformation after insertion into the casing (3) with its external diameter in a bore (16) in the casing (3).
