1. A pipe coupling assembly, comprising:

  • a first and second pipe, said second pipe having a plurality of radially extending ridges at one end thereof;

    a first and second body part, said first body part having a first end for connection to said first pipe and a second end for connection to said second body part;

    said second body part having a first end for connection to said first body part and a second end forming a socket for receiving said second pipe therein, in a push-in manner;

    said first and second body parts having a through bore for the passage of fluid between said first and second pipes;

    said first and second body parts molded from plastics materials;

    said second body part further comprising a sealing means and latching means for cooperating with said radially extending ridges on said second pipe, said latching means on said second body part comprising integrally-formed, internally-directed ribs which allow said second pipe to be pushed into said socket with said ribs yielding to allow said ridges to pass, but which prevent said second pipe from being pulled out, and said sealing means between said second body part and said second pipe comprising two O-rings seated in an annular recess on said second body part, said sealing means and latching means being arranged relative to one another so that as said second pipe is pushed into said socket, latching occurs between said second body part and said second pipe before sealing occurs between said second body part and said second pipe;

    and wherein said second body part is connected with and detachable from the first body part, such that said sealing means remains with said second body part when said second body part is detached from said first body part.
