There are two little grooves where you can pry with your fingernails when you look closely. Feels much safer than pulling.
those grooves are not actually attachments.
There is only one way to align them properly, it's clearly visible. They just need a gentle push to get back on, never use force!
I know, but nonetheless you can use them to pop the tips off with your fingernails
Invert, pinch and just pull
