Brake Line Clip removal

[Steve547i]

So my brake line is leaking on one of the spots where a clip holds it to the body. I was trying to pry but it was not work. Anyone have any tips for the clips?
Thanks

Memory says that the clip is help on with a screw, the rusted head of which is visible above.
