A pipe coupling comprises a screw-threaded member to surround the pipe and adapted for threaded engagement with a body bored to receive the extremity of the pipe, a tapered split collar for engagement with a corresponding taper on an inner surface of the threaded member to permit contraction on the collar into gripping engagement with the pipe and a separate non-split sealing device attached to the split collar to effect sealing engagement between the pipe and the body. The sealing device is removably attached to the split collar by being sprung into engagement therewith under radial contraction of the collar which expands again when a lip and rebate formation between the collar and the sealing device comes into operation. |
