ABSTRACT:
A coupling mechanism for the interconnection of sealing plates. Symmetrical coupling halves of the sealing plates are interconnected and welded together to form a hollow space that can be checked. Each coupling half has a free edge that is provided with a C-shaped profiled connecting part. That edge of the coupling half where it is attached to a sealing plate is provided with a notch-like part that is symmetrical to the C-shaped connecting part. A sealing strip projects into the hollow space from the transition area between the notch-like part and the adjoining wall. This sealing strip can be welded to the transition area of the cooperating coupling half between the C-shaped connecting part and the adjoining wall thereof.
