Use a good 2 part epoxy and clamp the new piece to the old one and let it dry per epoxy instructions before removing clamps. he longer you leave it NOT repaired the wider your crack will get putting stress on the seams of your glass. Once repaired, since the crack is that small, you shouldn't have any trouble. You can get epoxy (2 part clear) at Lowes, Home Dept, Ace Hardware and even WalMart (if you must). Those that have a longer setting time usually offer you more tensile strength.
