Any help with a noisy fixing clip on GypCeiling system

[nmh]

I think I've made a boob by using the Gypframe MF9 Connecting Clips instead of screwing the MF5 to the MF7 beams. It means whenever I open my son's room door, the ceiling squeaks!

See attached video with sound. 

 

Hard to use screws now because I don't have access from below because the new ceiling is in place. 

 

Can anyone think of a work around? Some rubber between clip and metal MF7 baton? 

 

Any help hugely appreciated.
