It will drain a little but only a few ounces, cut a paper coffee cup down and catch it in that. It can't actually drain your reservoir down enough to hurt the brakes' fluid supply, it's a kind of side impoundment inside the big tank that feeds only to the clutch line.
If you pull it off at the reservoir, you can attach it easily to your new clutch master cylinder outside of the car, then putting it back on the spigot out of the reservoir is much easier in the car than putting it onto the master cylinder would be.
But now you're where you're at, maybe just continue and attach it to the slave as you put it in. Don't worry about spilling fluid, just let it drain out into a little cup.
I am a big fan of Saab's original spring clamp on that hose, but it would be almost impossible to reattach down under everything there. But you can use the smallest worm-drive stainless steel hose clamps, which are commonly available in a size that will fit that hose, either at your local hardware store if Home Depot hasn't killed that off yet, or at an auto parts store.
Don't overtighten the hose clamp, you can actually cut a hose if you do. That's one reason I like the spring-type clamp, it's tight enough without going overboard.
If you're going to back-bleed as I describe below, don't bother to top the brake fluid reservoir back up to make up for whatever fluid you've lost. You'll be pushing fluid up into it from below.
I recently bled a clutch and decided I'm a big fan of CMyles's method: about 3 feet of clear poly tubing bought at said hardware store, (maybe, 1/4" i.d.?) that pops over the bleed screw on the clutch slave. Use box end of a 13mm wrench to crack the bleed screw loose first - - you can only turn a few degrees but should be able to get the screw to start turning. Then loosen it further with the open end of the wrench.
Pop hose over the bleed screw, then pour brake fluid out of the bottle into the hose till it's near full. Wipe end clean, put it in your mouth and blow hard - - your cheeks will hurt like blowing up kids' balloons. You should be able to watch the fluid move down the hose. Keep the pressure up but stop before it gets all the way back to the bleeder screw, and using hose, twist the bleeder screw just down onto its seat. Then pull end of hose off and use wrench to set bleeder down tight.
Clutch should be fully bled. If brake fluid reservoir is low top it up now. If it's overfull, maybe sop some out with twisted paper towel.
