A fluid-actuated cylinder and a method for manufacturing it, including a head (3) and a connecting tube (6) to be coupled; coupling is obtained by compression of the two members (3, 6) along their axis, deforming the end (16) of the tube by using, as a die for the deformation of the tube, a particular ring (1) which is fitted on the head member (3) and is coaxial thereto.
