ABSTRACT:
A quick fit pipe coupling has two parts with each body part retaining one of the pipes to be connected. The two body parts are screwed together. One pipe is to be push-fitted into the coupling. This pipe has radially extending ridges by which the pipe can be latched in one part of the coupling, and this one part of the coupling also carries the seals which provide the fluid tight seal. When the coupling is dimantled, the seals remain in position and are not disturbed.
