An exemplary arrangement for securing the shaft of an exhaust-gas turbocharger includes a catch ring with a central opening and a radial projection on the shaft. The catch ring having an inner contour in the region of the central opening. The radial projection on the shaft is provided with an outer contour. The inner contour on the catch ring and the outer contour on the shaft are configured such that, during mounting of the shaft and of the turbine wheel connected thereto and in at least one specified angle position of the shaft with respect to the housing, the radially outwardly protruding projection on the shaft can be passed in an axial direction through the central opening of the housing element. The radially outwardly protruding projection abuts in the axial direction against the housing element in specified angle positions of the shaft with respect to the housing.
