摘要

The invention relates to a device for tightly closing a connection of a thin-walled channel pipe to a connection pipe in which a branching opening is to inserted. In order to be able to easily and securely insert the inventive device into the branching opening, the following individual parts are provided: A connecting sleeve (20) with a connection pipe in which a sleeve pipe thread is at least partially arranged, on which a tightening thread is at least partially arranged, and on which an outer flange (20) which runs compatible to an inner wall contour of the channel pipe is arranged; the connecting sleeve (20) is produced with a sleeve wall thickness such that it can be compressed and pushed into the branching opening (14); a supporting ring (30) with a supporting flange fitted to a contour of a channel outer pipe surface; a tightening ring (50) with a ring in which an inside thread is at least partially arranged, and on which a circumferential supporting flange (54) is arranged such that it seals, whereby the supporting flange (54) is to be laid on a support ring of the supporting ring (30), said support ring being situated opposite the supporting flange, and the end of the connecting sleeve (20), said end being situated opposite the outer flange (22), is to be drawn up by screwing the inside thread on the support pipe thread, and a ring sealing element (24) is to be fixed to the outer flange (22) in a sealed manner; a branching support (40) with a branching pipe on which a screw-in outside thread is at least partially arranged and whereby the branching support (40) is fixed in the connecting sleeve (20) by screwing the screw-in thread into the support pipe thread.
