securing top of 40gal glass tank

[Vypyrz]

I have a Hogg Island boa in my 40 gallon breeder and I have 6 cage clips/clamps holding it down can never be too safe also a certain someone I live with is afraid its going to get out and eat her cat so the clips/clamps work fine

She has a DIY top that they built. I don't know if the cage clips are going to work or not...
