Abstract: A pipe coupling assembly for plain end pipe of the type in which a packing ring is compressed in an internal groove by a thrust ring to squeeze it against the outer surface of the pipe and effect a seal therewith. The thrust ring is made of a plurality of accurate segments which can be economically produced and assembled in the coupling body. The segments are mechanically interlocked in the body by cooperation with other elements of the assembly to avoid separate retainer members. The segments have a configuration which avoids significant circumferential gaps in the packing compression face of the ring and reduces the necessary axial length of the groove.
