The present invention provides a pipe coupling comprising a tubular body having an open end, sealing means within the tubular body and pipe engaging means operable between a pipe clamping configuration in which an inserted pipe is clamped and a pipe release configuration in which an inserted pipe is not clamped and is releasable. A seal protector means is operable between a seal covered configuration in which the sealing means is at least partially covered and shielded from contact with an end of an inserted pipe, and a seal uncovered configuration in which the sealing means is uncovered and in contact with the inserted pipe. Moving means arranged within the tubular body is activated when a pipe is inserted a predetermined distance into the tubular body to move the seal protector means from the seal covered configuration to the seal uncovered configuration and the pipe engaging means from the pipe release configuration to the pipe clamping configuration. |
