I have sunk years of research into this and I still can't figure out any convenient way to attach my portable dishwasher inlet hose to the sink faucet.
I originally just had the Bunnings Kinetic 19mm Brass Dishwasher Adaptor, as the only attachment - but I had to carefully screw it on the hose and tap every time I wanted to use it.

Now I've got this plug-on arrangement I bought online, which involved buying a set of MORE brass adaptors to screw onto the original Bunnings one, AND 2 rubber fittings to plug onto the tap, AND a beige plastic screw-on clip to screw AROUND the whole thing.

This is way too many attachments and was still very inconvenient to plug on, and screw the outer part around it all (pictured above - it's a column of white rubbery parts and various brass and metal adaptors). And of course the inside of the rubber fitting ripped, so it's no longer a tight seal; water sprays everywhere so it's unusable.
I wouldn't even know the name for the little inner rubber piece, so I can't simply buy a new one - I'd have to buy a whole set of parts and attachments again, in the hopes of getting another cheap little rubber piece. It's also hard to buy these things online because of getting the measurements correct.
SO I bought ANOTHER brass fitting and a snap-on adaptor, the convenient kind that is meant to be attached to a hose (pictured below) - but how can I attach it to the dishwasher inlet hose?! Am I meant to cut the end off of the hose?

Someone please help, I've been at my wit's end with this and can't google any more solutions (especially with my limited knowledge of any kind of technical plumbing terms). I just want to know how to attach the snap-on adaptor to my hose & finally be able to use the
dishwasher.
