Abstract
A coupling sleeve for connecting thin-walled the ends of pipes comprising a circularly bent sheet-metal strip and a sealing strip lining the inside thereof. A turnbuckle on the sheet-metal strip causes the coupling sleeve to be tightened against the pipe ends. A loosely attached spacing member located approximately at the axial middle of the coupling sleeve in the region of the turnbuckle has an end that projects through the sealing strip into the interior of the coupling sleeve in the untightened condition and is pressed outward, during the tightening of the turnbuckle by an end of the sheet-metal strip and is forced into the elastic inside surface of the sealing strip or into a slit in the sealing strip.
