A frame comprising at least two sectional elements which are detachably interconnected and pressed against each other, the end-face and the outer surface of one of the sectional elements are differently shaped in such a manner that when the sectional elements are clamped together by a bolt, the end-face first bears against one of the sectional elements along lines of contact and rotation of the elements relative to each other is prevented, and upon further clamping, the vanes or rails bear against the end-face by becoming elastically deformed.
