Flexible conduit means for an exhaust system of a combustion engine vehicle, comprising: a bellows member extending in an axial direction, an outer flexible braided or knitted member that encloses the bellows member at least partially, at least a resilient member, that is elastically deformable and encloses the outer braided or knitted member at least partially and abuts against it, whereas the bellows member comprises: at least two corrugated portions that are annularly corrugated in the axial direction of the bellows member by alternating ridges and recesses along the outer periphery of the corrugated portions at substantially regular intervals, at least a connecting portion that is formed axially between the corrugated portions of the bellows member, the resilient member encloses the connecting portion at least partially, the connecting portion comprises flanks that are formed at its axial ends, and which extend at least in a radial direction, and the connecting portion between the flanks comprising a curved and/or arched portion that is curved and/or arched in the axial direction, which connects the flanks with each other and which is at least partially enclosed by the resilient member, and the axial length of the connecting portion differs from the regular intervals of the corrugated portions, characterized in that each of the flanks are connected in the axial direction to the adjacent corrugated portions by an at least partially cylindrical portion, the axial length between the flanks of the connecting portion is 30 percent to 80 percent of the axial length between the adjacent corrugated portions which are connected to the cylindrical portions, the smallest diameter of the connecting portion is larger than the smallest inner diameter of at least one of the adjacent corrugated portions, and the cylindrical portions are shorter in the axial direction than the curved and/or arched portion of the connecting portion. a bellows member extending in
