My fuze powerbutton broke

[m60]

I accidentally bricked my Sansa Fuze. I succesfully opened it and manually unbricked it thanks to the article in the wiki.
The problem is that when i opened it, I broke off the little plastic ting on the power/ hold switch, that goes goes into the slider.


The broken off part is kinda bended and when i glue it on, it only stays there for a short time before breaking off again.
Does anyone have any ideas, as to how I could possibly fix this?
