Garden Hose Fitting Grip

After using rv drinking water hoses with a similar piece on them to help tighten and loosen, I realised how heplful they are. This is designed to fit on a 30mm garden hose female side. I have a flex zilla hose but i think the are standard sized and it will fit other brands. 

To use it simply slide over before connecting hose. The grip has stops to keep it from sliding past the fitting. You could also glue it on with some super glue if you want a tighter fit.
