Ive had some CK brass fittings for 30years which were quite expensive but are excellent. Ive also bought cheap ones but found the ball bearings rusted easily and seizedTry a brass one?
If you find the pipe is slipping out of the fitting , slip the female threaded part down the hose ,dip the end in a cup of hot water then slip it into the fitting and tighten it all together and let it cool plunge into cold water before pressurising.I have had issues with hozelock just slipping off the pipe, and with staying put with other hozelock it, in this instance it isnt, but I have had too many problems with their stuff. I think they are doing a Black and Decker, eventually they will have to rename...
