A tip for anybody wanting to join two different hoses with barbed joiner and o clips..... Sometimes this then gets snagged easily. I bought some polymorph ( google it and buy from eBay ) plastic grains that melt in hot water and are then moldable until cool .... Wrap this over the join. Will minimise snagging, strengthen and protects the fitting against wear and leaks. Simply put in hot water again to melt and remove it - re usable too.
