I too, had this same problem when trying to change my upper radiator hose. The red lower release lever was quite brittle and broke off when I tried to loosen it. I made a little tool from a piece of stiff aluminum and pushed down on each tab in the slot and they each released without a problem. I guess that you could make/shape a similar tool from any really stiff and strong material. First, I used my grinder to dress it down to the correct width and thickness so that it would easily slide into the slot for the tabs, seen in the second pic below, then just push down on it.
Note: Make sure that the tool isn't too thick for the slot, since that would damage the plastic housing and create a new headache for you. I would suggest that you reach under the bracket to feel for the tabs as you are pushing them out, to make sure that you are not pushing them entirely out of the housing. Once they have each been released, the bracket will pop out. To reattach, simply push the connector bracket all the way back onto the ECU, while pushing up on the tabs beneath (you have to do them one at a time). I couldn't get either of them to go all the way back in, only about half way, but the connector seemed quite secure when I pulled on it, so I don't think it will shake loose. Hope this helps!
