BTDT. I broke off the bolt and then tried an "easy out", which snapped off. The problem is, the "easy outs" are hardened steel and can't be drilled through with High Speed Steel (HSS) bits.
What I ended up doing is taking my Dremel tool and chucking a small carbide grinding bit into it, and grinding away the remainder of the "easy out" stub. Be careful not to mess up the interior threads of the hole. Once you grind away enough of the bolt remnant in one spot then the pressure holding it in will be relieved; if you try a left-handed drill bit on it, it should come right out.
I've had trouble with those speedfit connectors, too.
