Help with under kitchen sink leak

[ozmarsh]

I am a complete novice when it comes to anything DIY. Only just moved into a place of my own. I heard a leak while using the seal to find it was coming out of here.

Can anyone tell me what its for & why wouldnt it be connected at one end?

How can I stop the leak?

TIA

Yes it’s the overflow piece. Try looking in line where the overflow is on the sink.
