Abstract: A coupling member for model railway rolling stock comprises an anchoring member for attachment to the end of a model vehicle, a rigid bifurcated member extending from said anchoring member and a resilient tongue extending substantially parallel to the bifurcated member at one side thereof and at a spacing therefrom. The tongue is flexible away from said bifurcated member and carries a latch which is directed towards said bifurcated member. The other side of the bifurcated member is recessed to define a catch. When the coupling member is engaged with an identical counter-coupling, the latch of the counter-coupling is engaged in said catch of the coupling member, one bifurcation of the counter-coupling is engaged in a receptacle defined by the bifurcations of the coupling member, and the other bifurcation of the counter-coupling is engaged in the spacing between the bifurcated member and resilient tongue of the coupling member.
