Wall mounted plant pot holders

I'm trying to find plastic plant pot holders. The type that have a small clip that screws to the wall, fence etc and then a flat, circular strip roughly 25mm wide fastens into the clip. The plastic strip expands to take different sizes of pot.

The ones I have, I use for wildlife photography set-ups. I've searched everywhere but can't seem to find them any more. I think the original ones I still use came from an advertisement in one of the Saturday newspapers.

Anyone any help or advice please?

 

I have these
Home . Hang-A-Pot: The Hidden Hanger . Hang flowers and plants anywhere!

Maybe email them and ask if they have a outlet here?

 

I got mine at the Ideal home exhibition many years ago.

I had them up on the balcony at my flat. That flat was a wind trap and those pots ( not plastic either) held fast . I always thought they would one day come through the window but nope there moved from side to side a bit but that was it.

They hold any size pot, never see them anywhere else they just didn't catch on.

 

Found these:-
Pot Clip - Set of 3

 

Thanks for the help everyone.

The photo below shows the red clip and circular strip. I believe they also used to be available in a solid black colour as well.

 

I have a couple of these holders

Wish I could get some more
