    Abstract: A mechanical repair fitting for arresting propagation of a damaged section of flexible pipe such as polyethylene pipe is disclosed wherein mating cylindrical half-pipe sections are hingedly coupled together so as to flex open for receiving said damaged pipe. The fitting is then locked onto the pipe section thereby compressing two annular seals to form a pressurized compartment between the fitting and the pipe. A valve forms a port to the pressurized compartment and permits the control of pressure therein. If the pipe is breached, the compartment will have the same pressure as the pipe during fluid flow such that strain due to a pressure differential is alleviated. If there is no breach but damage, the pressure can be equalized with the internal pressure to prevent propagation of the damage.
