Mechanical clip for holding U channel parts together for LED fixture

I never have had much success in gluing PETG together for structural reasons, so I have designed this really simple clip to supplement the holding strength. Thanks for the original designers of both the U-Channel mod and original LED light bar! https://www.prusaprinters.org/prints/3267-led-light-bar-prusa-i3-mk2mk3 I suggest printing it in PETG for robustness, but I guess PLA would do the trick too.
