Does that mean that there is no connection between satellites?

Correct. The intersattelite laser link is still vaporware at this point, and I’d wager always will be. It turned out to be a much more difficult problem than they originally anticipated, and so they’re basically not doing it. I will be very surprised if it ever happens.

That they had a successful “test” of it a year and a half ago does not mean it’s in use now. Current starlink is just receiver -> satellite -> ground station, there is no lasers in use.

Why do people keep betting against Elon's plans, they always lose in the long run.
nothing obviously satellite related shows up at layer 3. There's a few hops of stuff with no rDNS, and then the edge of the AS36492 network and whatever transits or peers your traffic is going to.
You can clearly discern from pinging your first hop (15.9 to 30ms away) that it's something on the other side of the up-and-back satellite link.
topology at present is logically a bent pipe. satellites need to be simultaneously in view of your terminal and a spacex earth station. The ten satellites they launched into a polar orbit last month are the first with inter-satellite laser links.
