ABSTRACT A coupling sleeve for connecting thin-walled pipe ends with a circularly bent sheet-metal strip (10) and a sealing strip (30) lining the inside thereof, and with a turnbuckle (18) for tightening the coupling sleeve on the pipe ends to be connected. A loosely attached spacing member (32) located approximately at the axial middle of the coupling sleeve in the region of the turnbuckle (18) projects through the sealing strip (30) into the interior of the coupling sleeve. The end (36) of the spacing member (32) that projects inward in the untightened condition is pressed outward, during the tightening process, by the increasingly overlapping ends (14, 16) of the sheet-metal strip (10), in such a way that it is forced into the elastic inside surface of the sealing strip (30) or into a slit thereof.
