ABSTRACT:
The device is arranged in a process engineering column (10) and serves in particular for the guiding of liquid. This device includes at least two parts (1, 2) made of sheet metal and releasably connected to one another. A recess (12) is arranged in the one part, the sheet metal part (1) of a first kind, and an elevation (21) fitting into the recess is arranged in the other part, the sheet metal part (2) of a second kind. The two sheet metal parts are held in a secured position by a hook connection between the recess and the elevation. The recess and the elevation form a single pair or one pair among several and the sheet metal parts have planar regions lying on top of one another in the neighbourhood (120, 210) of the pair or of each pair respectively.
