This product is not perfect. But the foam it produces is of high quality considering it's attached to a garden hose. If you plug this in the US you will find that the plugs do not work. The one that connects to a 1/2" garden hose is cheap plastic and not worth the hassle of installing it. It won't stay. I bought this connector kit. It works great now. https://www.amazon.com /gp/product/B07R33KYHM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I originally bought the more expensive foam soap as shown below I don't think you need that kind of quality a cheaper version would work https:// www.amazon.com/gp/product/B003TPW5YM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 Regarding the foam nozzle, locking mechanism, there are several holes that can be used to install a safety wire to prevent this if this happens I'm not sure if the glue will work, I don't know what plastic they are made of.
