Removing vertical blinds

[user1489844432]

Hello

I am really desperate for some help. I have vertical blinds that were put over 5yrs ago. One got broken and I need to remove it but I don't understand how they are fixed to the window. All YouTube videos I have seen show either brackets used or a screw put at the front of a fixing to hold it together. Mine have completely different mechanism.

Any ideas pls?

You pull forward the right-hand lever (the one with the dimple on the top), that releases the top-rail from the bracket(s).

Well that was easy!

Is there a name for this type of mechanism/fixing system? Ideally I need to find YouTube video to see how this is done. I swear that lever is not moving, I must be doing something wrong!

That can be quite stiff plus's the dimple is there to stop it being unlocked in error.
Slide a flat screwdriver underneath it to provide leverage.

Dunelm may show it in the on-line installation guide as they use the same fixings.
