A device for erecting walls and/or ceilings includes a support shaped-section evincing approximately cross-sectionally T-shaped webs to which at least one beam for wall- and/or ceiling segments can be detachably affixed, further a clamping lock detachable fastened inside the hollow beam and comprising a central retaining element and two spring-steel, lateral retaining elements mounted symmetrically relative to central retaining element. The retaining elements engage adjacent and undercut channels formed by the webs and are tightened against two adjacent webs of the support shaped-section by a rotationally actuated, transverse tightening system crossing the three retaining elements through mutually flush clearances. At the same time, the tightening system affixes the clamping lock inside the beam. The two lateral, elastic retaining elements are joined in integral manner at their rear ends away from the support shaped-section and are mounted in a clamping-lock housing also receiving the central retaining element and the rotatable tightening system. The tightening system comprises a central, cylindrical part crossing the three retaining elements through mutually flush clearances and furthermore two external washers enclosing between them the two lateral retaining elements, the inside surfaces of washers each resting against the associated lateral retaining element. Each of the inside surfaces of the two external washers comprise an actuation plane corresponding to one of the associated lateral retaining elements.
