How does one remove a broken vane carrier clip on a Vertical Blind system?

The vane carrier clip is the plastic clip that holds the vertical blind. I have replacement carrier clips that I bought in a Vertical Blind Replacement Parts set but doesn't tell me how to remove the broken clip.|||Depends on the parts used . some of the new fittings are simple that you push a smallscrew driver in and the hook pulls out. some of the old ones you have to pull apart. Ask your retailer who supplied the parts how to remove it if you cant do it
