Clamping units are mounted without fasteners in the joints between wall panels and grip adjoining panels in coplanar alignment. The clamping units are inserted through accessways between the panels and are operated by a tool passed through the accessways. The clamping units are also used to hold upper locking units, each having a slide bolt which engages a ceiling rail, and to hold bottom locking units which engage a bottom rail on which the wall panels are seated. Each panel can be removed independently of the others by tilting after removal of the respective clamping units and associated locking units.
