For rapid assembly of the deck of a drilling platform on a pipe scaffold, a connecting element made of two interlocking parts is described. The first part is in the form of a closing head integrated by casting into the end of a vertically standing pipe of the pipe scaffold, a ring-shaped horizontal support surface and a lifting bitt extending upward. The second part is in the form of a bell-shaped cover which envelops the lifting bitt. The cover on its upper surface is welded to the drilling platform, and at its underside includes a supporting surface which bears upon the supporting surface of the first part.
