I used a piece of white synthetic DIY cord similar to bathroom light pull cord. Used existing stitched tunnel holding buckle. Hacksawed old buckle off. Threaded cord through attachment end of new buckle, passed both ends through tunnel and tied tightly through attachment end again with fisherman's, pushed knot into tunnel for neatness. Repeat for other half of buckle.
Used on backpack waist strap and has lasted years.
Edit: Realize I didn't need to use this on other side of my buckle as that needs to slide along strap.....I managed to force the doubled over end through attachment part of this half of buckle.
