Jay, that's the type of clamp that blew apart on me. Coincidentally, the same thing happened on the same night to a member over at Subaru.com
Unfortunately, his was on an engine oil line and it ended up killing his engine
Getting the subaru style off can sometimes be a problem, but if they're rusty a quick snip with the dikes and they're off, something you can't do to a tight worm clamp.
