A plastic pipe coupling comprising two large pipes (10, 12), the pipe ends of which are placed against each other and joined together mechanically. According to the present invention, the tubes are joined together by a snap connection (14, 16, 18), which is comprised of a male part (14) that is inserted into a female part (16), wherein the female part is slitted (18) from the edge axially to allow radial movement of at least part of the edge of the female part, when the male part is engaged. The present invention provides a coupling with a stiffness and tensile strength suitable for large pipes having diameters of the order of 300-3500 mm and having a considerable weight. |
