Such assembly removably secures a male connection member to a female connection member of an articulated coupling arrangement. Such articulated coupling arrangement used to secure one end of a first railway car to an adjacent end of said railway car in a semi-permanent fashion. The assembly includes a wedge-shaped member having a surface engageable with a surface located in an opening in a side wall portion of a cavity at an outer end of the female member and another surface engageable with a surface on a shaft member of a spherical bearing carried by such male member. An aperture is formed through such wedge-shaped member along a longitudinal axis thereof. A bolt member is disposed through this aperture and an aperture formed through a bottom wall on the outer end of such female member adjacent the side wall opening. At least one force exerting device is positioned intermediate either the top surface of the wedge member and the bottom surface of the head of such bolt on the bottom surface of the bottom wall and the top surface of the nut carried by the bolt.
