Huh? That statement is very confusing: I think you mean to say...
"This clamp is used as a wedge to pry the two case halves apart."
There. Also, a "spanner" is usually a British English term for a what the Americans call a wrench, like a combination open end wrench with the other end being a box end (google it). The tool you translated is more accurately described as a Torx bit T-handle driver (the cheap version with no rubberizing or comfort grip: anybody wanna line up to remove a mega-over torqued bolt with that wire framed version? Not me).
The SE and SE/30 have a T15 size machine screw, I don't know if the Classic is the same, but giving people a reference helps sometimes
