Any one understand in plubering? If not, are you very smart?

Here is 5 picture posted bellow helping visualize the scene. But before, I will introduce you to the problem.
Home flood due the sink of the bathroom. We think, it’s because of the silicone filling inside the sink or it is because something got unscrewed. So we went down there and tried to tighten few things. We broke the yellow thing. Thought, the problem is not from that, since it was not broken before.
We tried to screw the yellow thing more and that is how it broke.
Anyway, is there any possible way to fix this without getting a plumber? If not, do not suggest getting one!
Thanks guys.

Answer #1
WTF is plubering?
Answer #2
As far as I can tell by examining the photos; remove the leftover yellow piece, take a knife and make a straight ending on the yellow hose, heat it up and slide it back on. Let it cool off and tighten, but not too firm or you damage it again.

correct as far as it goes
heat it up
it may go on with out heating, but you can get a cup of hot water to “soften” the tube up if needed
just stick the end of the tube in the water for a minute of so
remove the leftover yellow piece,
on the remaining (leftover) yellow piece is a ferrule (a flat wide ring)

in the pic above it’s brass, where yours is plastic

it has to be on the end of the tube to hold the tube in place by compressing as you tighten the nut

To me the plastic of his tube looks harder than the one you’re showing in your screen shot, based on the translucency of his tube and the way the tube is broken.
Answer #5
Go get a another piece of the plastic pipe longer than you need and 2 more compression rings and repair the pipe. Plastic pipe is cheap and those small fitting are easy to find. The smaller Mom and Pop hardware usually have the rings separate.
Answer #6
Thanks guys, I will try these out.
Answer #7
If you’re still reading this….
Based on pic #5…..
take a pair of pliers and gently twist the short (right) broken end that’s in the valve. It should come right out.
Inside of it you’ll find a small brass fitting shaped like a hollow top hat. Save it to reuse if you didn’t damage it. If damaged, take to a hardware store for a new one. These are all a standard size.
Flush cut with a knife the end (left) that has the nut. Insert the brass fitting back into the tube. The flange on the fitting (top hat) will stop it from going all the way in.
Slide the fitting end (left) back into the valve (right). push it in tight and hold it while you tighten the nut.
Don’t over-tighten.
Turn the water back on an check for leaks.
