O-rings. The straight(er) one also has a bolt to fasten it to the block.

(That's for a 528i M52TU engine but probably identical to yours in this area. You can back up and enter your VIN or car details to get specifics. The section is engine cooling, under engine.)

Regardless of what the AutoSport man says, these pipes are aging plastic. One may be leaking now but if it decides to open up, it will release coolant very quickly and your engine could overheat before you realize it. Sorry to shake your faith, but these i6 engines will blow a head very quickly if you let them overheat.

If you have another car, you should consider driving that one until this one is fixed. That's my 2 cents.
