1. A gangway for a multi-car vehicle, the gangway comprising a bellows and an endframe, the bellows being attached to the endframe, wherein a crimping element is attached to the endframe, the crimping element having a crimping mouth, wherein a part of the bellows is inserted into the crimping mouth and held inside the crimping mouth, wherein the crimping mouth is defined by two sidewalls arranged next to each other and joined together at one of their ends by a bottom wall, wherein respective opposite ends of the two sidewalls are not joined together to provide an opening of the crimping mouth, and wherein the crimping mouth is designed to cause the part of the bellows that is held inside the crimping mouth to be pressed together between the two sidewalls of the crimping mouth by a pinching effect resulting from a force provided solely by spring properties of the crimping element, the crimping element formed of a material having spring properties such that one of the two side walls can be moved away from the other one of the two side walls only by tensioning the two side walls against a restoring force provided by the spring properties of the crimping element, wherein the crimping element is attached to an exterior side of the endframe by a screw having a head in an interior side of the endframe.
