Abstract
A fitting connectable to an end portion of a pipe generally includes an insert member configured to be received at least partly within the end portion of the pipe, and a retention member coupled to the insert member and configured to be received at least partly within the end portion of the pipe. The retention member operates in conjunction with the insert member to engage the end portion of the pipe and impart an increased force against an inner wall of the pipe in response to an increase of internal pipe pressure, thereby frictionally securing the end portion of the pipe on the insert member as internal pipe pressure increases during use.
