The present invention relates to a train coupler adapted for energy absorption by the use of a deformation unit. According to the invention an axial expansion module is provided and mounted together with the deformation unit and an anchor in the housing of the train coupler. By expanding the axial expansion module after being mounted into the housing, the deformation unit and the anchor will be biased between the front and rear lugs of the housing and held in place by a predetermined force in the axial direction only.
