a coupling for joining pipe elements in end to end relationship is disclosed . the coupling includes a sealing member having an inner diameter and an outer surface . a plurality of segments are supported on the sealing member &# 39 ; s outer surface . each segment has a pair of arcuate surfaces positioned in space relation on either side of the sealing member . a compression band surrounds the outer perimeter of the segments , the segments being captured between the band and the sealing member . the pipe elements are inserted into the inner diameter between the segments . a tensioning member is mounted on the band . tightening of the tensioning member causes the compression band to force the segments radially inwardly into engagement with outer surfaces of the pipe elements .
