Here's a quick tip when buying ring clips to clamp the end of a flexible hose to a camlock fitting. If your water pressure is high then it's important to buy heavy duty rather than standard ring clips, and to tighten them at least once more (after the initial tightening) after leaving the hose and fitting in the sun for a while (after the first tightening).
Below is a photo of one of our hose fittings. We also elected to use 2 rather than 1 ring clip per end fitting. Better to be safe than sorry. In our case we started with standard ring clips but the water pressure blew the fitting off when there was in excess of 50 metres of head pressure.
