ABSTRACT OF THE DISCLOSURE A hollow plunger extends into the cavity of the draft gear body. The inner end of the plunger is expansible. One or more wedges are held by the body adjacent the inner end of the plunger, and shoes are positioned between the wedge(s) and the inner side of the inner end of the plunger. Spring elements positioned within the plunger are in compression be- tween the outer end of the plunger and the shoes. When the plunger is forced into the body the shoes are wedged outwardly against the expansible portions of the plunger which in turn are forced into contact with the body. There may be one or a plurality of successive stages of wedges and shoes.
