I recently had a flooding in my apartment due to a broken hose under the kitchen sink. Now I'm worried about everything that could go wrong again in that sense.
Then I noticed this device that sits between the tap in the bathroom and the hose that connects to the washing machine. I thought this was something to prevent water leakage in case the hose would be damaged. But then I disconnected the hose from the machine and let the water run freely to see if it would automatically stop at some point, but it didn't. I couldn't notice any limitation on the water flow.
Tried to look for that online but couldn't find anything. The only similar device to this was one that allows water to go only in one direction, but that device usually had a switch and this one doesn't have anything. There is a device just like this one attached to the water supply for my dishwasher.
Can anyone tell me what is this thing and what it does?

It appears to be an "aquastop valve" that shuts off the water supply in the event of a leak. Many brands appear to do this. Here's one example.
I don't know how it works, but WhitegoodsHelp has some more info. The dot on top of yours looks like a trip indicator. Also it only detects a leak in the inner pipe itself and won't react to your disconnecting the other end to test it (which is a good thing since apparently you would then need to replace it as there's no reset button).
