There are a couple of things you can do.
The way to be certain that there will no leakage at all is to use a nut and bolt through the ends of the brake lines with some new copper washers (like what is already on there). Tighten it down good enough to deform the washers and create a seal on both sides of the fitting (factory torque spec used on the lines to calipers should be enough)
You can also buy rubber plugs that fit the end of the lines. I got these and used them while I was rebuilding my calipers. It worked OK (over night), but it didn't seem like they were very tight to me. It I was planning on having it pulled apart for more than a day or two I'd probably go with a nut bolt combo to make sure they were sealed (might even put some liquid sealant on the threads of the bolt that were going to be touching the nut just to be sure).
Good luck

I use the old crush washers with a bolt and nut as suggested above, since I replace the crush washers any time I unbolt the banjo bolts. That, and put a can or bowl under each line so if it drips, it drips into a container, not on my garage floor or driveway.
Personally, I would hesitate to use vice grips when a bolt and nut is so cheap and makes it easier to regulate clamping pressure.
