Check out Maxpedition's Tac Ties.
They are designed to connect molle gear, and I've used the 5" version with my 5.11 kilt's D-rings.
Usually $7-$8 for four.

"O God, give me these boons: Never shall I shirk from doing good deeds,
Never shall I fear when I go to fight the enemy, and with surety I shall attain victory." - Guru Gobind Singh.
