Hose burst protection 1/2 inch?

Hello everyone!

I recently placed a countertop dishwasher in my kitchen. Since I had no space near the sink, I had to use a longer inlet hose (3m). Since there is no water connection under my sink, I wanted a solution that would allow me to connect and disconnect the hose repeatedly. So far so good, everything worked out. Now I only have the problem that I can no longer install an Aquastop because my faucet is only 1/2 inch. The hose that came standard with the dishwasher also did not have one built in.

Is there any solution for this? Or is it not that critical? Unfortunately, I don't know exactly how to proceed now.

Thanks in advance.

Oh yes, I searched endlessly to find an Aquastop in 1/2 inch.. but unfortunately without success. Of course, I could go from 1/2 inch to 3/4 inch, Aquastop, and then from 3/4 inch back to 1/2 inch, but isn't there anything simpler?
