Repair cracked clips with glue?

[badbob001]

In this motorcycle part, one of the clips has cracked and barely hanging on:

Can it be repair with glue? I read that LEGO uses Methyl Ethyl Ketone for glue, so I bought this:

BUT it didn't work. I pulled open the cracked part, apply the solution with a cotton swap, and applied pressure on the piece for a minutes. And it didn't do anything at all.

Perhaps I got the wrong product? Is this even worth the effort?

It contains Acetone, Methyl Ethyl Keton, and Cyclohexanone.

To be brief:

Probably not worth trying to repair. Acetone will melt (chemically) ABS, but it also makes it more brittle, so exactly what you don't want in a flexing piece like a clip. You're unlikely to ever get the right combination of elasticity and strength back into the clip. If it were a larger piece, maybe.

An ABS glue/welder of some type is usually a mixture of acetone and/or MEK with a percentage of ABS dissolved in it and might work better for this, but would also be tough to apply in that small area. Some folks make their own (mostly in the 3D printing field using spare filament, but I've seen folks do it with Lego as well) by just letting some ABS sit in the acetone or MEK and stirring, but I'd imagine that takes some finesse to get right as a usable substance.
