A displacement device for a fifth wheel traction coupling with two base bars and a fifth wheel traction coupling supporting top part which includes two bearing chocks which are slidingly fixed to the base bars and telescoping in a locked position thereof into each base bar by means locking elements with the aid of a rack rail. The known per se sliding devices are expensive due to the production of the base bars, since the rack rails are provided with a toothed profile prior to be welded. A low-cost sliding device is producible in a simple manner. For this purpose, at least one base bar is provided with spaced rest windows on the axial extension thereof for receiving the locking elements.
