Abstract
A coupling device for scale model railway cars has a hook-shaped coupling element with a free end, a shaft connected to the coupling element, a crosspiece extending horizontally from both sides of the shaft. There is a chamber having a rear wall which defines an abutment surface facing the free end of the coupling element and a front wall opposite and spaced from the rear wall and defining at least in part a through opening for the shaft. There is at least one compression spring coupled with the shaft and/or the crosspiece and bearing against the front wall. The chamber houses the abutment surface, the crosspiece and spring, the latter seeking to hold the coupling element resiliently in the normal position but permitting a swiveling of the coupling element about a vertical axis against the force of the spring while the crosspiece is urged by the spring against the abutment surface.
