Thank you (again) for being on top of things!
I actually have a nice assortment (something like this
). I wasn't aware that these are called Quick Disconnects in English. In Dutch we often refer to them as AMPs, possibly because they are produced by AMP.
I was aware that these will work, but I was hoping to find the exact boxy model like that are used in the picture. Sucker for trying to stay close to the original I suppose
