A mobile partition wall includes a plurality of adjoining wall elements 1. In order to prop and stabilize each wall element 1 between the ceiling and the floor and to provide noise insulation, each wall element includes an upper seal bar 8 and a lower seal bar 9. The seal bars 8 t 9 cooperate with a pneumatic stroke or force device 20 via a linkage 16, 16'. The stroke device 20 preferably includes a pneumatic bellows. A pneumatic coupling is arranged on each of the two narrow vertical edges of each wall element 1. When adjacent wall elements are pushed against one another, the respective adjacent couplings engage or couple with one another, whereby a non-return or poppet-type valve is opened to allow the flow of pressurized air. The pressurized air actuates the stroke device 20, which extends the seal bars 8, 9 outwardly to press against the upper support track and the floor.
