Abstract
A gangway for a multi-car vehicle has a bellows attached to an endframe and a crimping element attached to the endframe. The crimping element has a crimping mouth. A part of the bellows is inserted into and held inside the crimping mouth. 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, and not joined together at opposite ends to provide an opening of the crimping mouth. The crimping mouth causes the part of the bellows that is held inside the crimping mouth to be pinched together, and is of a material having spring properties such that one of the side walls can be moved away from the other one of the side walls only by tensioning the side walls against a restoring force provided by the spring properties of the crimping element.
