The invention relates to a pipe coupling for plastic pipes which comprises a glass-fiber reinforced plastic sleeve (2) and a membrane (4) which is produc ed from an elastic material. Said membrane is configured as a seal on at least one side and is provided with a jointing sleeve (8). In that portion of the membrane where it is configured as a seal, a short section (14) is shaped cylindrically at the margin of the membrane where the tube (20) is inserted (that is at the outer end of the membrane). In said cylindrical part the membrane has a constant wall thickness on which the glass-fiber reinforced sleeve part of the pipe coupling comes to rest. |
