Bumper falling off

Half of my bumper is hanging off ( the clip that holds it to the body on the tip broke off ) right now it is ghetto fixed temporarily. I need a permanent solution any ideas. One of my thoughts was to use some body filler all the way around the crack where the bumper attaches to the body....that would hold it right? and i think it would look nice without the lines...if it worked i would do it to the front too? so let me know if that would work or any other ideas

Do not do that. why? because you have no idea what to do and it would end up cracking to shit. Get new clips and put it back the way it was before
