Would one of our resident sparkies be kind enough to identify this PVC conduit fitting please?

I was given these about 20 years ago by an electrician friend. I have used them all now bar the one in the photographs.

This one is for 25mm Conduit. I would like to buy some more of these and some for 20mm conduit.

I can't find them anywhere on line, or even any pictures of them, to track them down and order them.

Can someone please tell me what they are called and possibly provide me a link?
