Kitchen sink is no longer attached

[ShrimpBurrito]

I looked under the kitchen sink earlier to find a few channels of metal that were attached (pressed?) to the underside of the sink. They came loose from the sink. Special bolts/clamps slide in these channels and press up against the underside of the counter to hold the sink down. Household sinks are mounted similarly.

I tried gluing one of these channels back onto the sink with JB Weld, but it popped off. I'd prefer not to drill a hole through the sink lip as any screw or rivet I'd put through it would then be visible on the topside....defeating the whole purpose of how it's supposed to work.

Has anyone experienced this? I'd be tempted to leave it as it, but I don't want to eventually work some plumbing loose. Any ideas?

Thanks,
Dave
