Abstract: A convertible partition wall is assembled alternately from vertical tubular supports and wall elements attachable thereto. The wall elements are fastened to the supports at least at their upper and lower edge by fastening parts. The fastening parts each grip a push-on sleeve which can be pushed onto the corresponding end of the support and on which at least two laterally projecting fastening flanges for the attachment of the wall elements are provided. A profile frame enclosing the wall elements partially engages round the adjoining supports with laterally projecting support webs.
