Swap the end of your flex arm.? It is a YS connector, named after the series of Sea & Sea YS strobes. You could find a ball end for your flex arm and a ball clamp - but putting a ball clamp on the end of a flex arm seems silly. You may find that the best solution involves tossing your flex arm and starting over with a ball arm system? Or find a YS mount for your light. The solution will be expensive.

I think this is the wrong part? And I have no idea what you would use it for.Mangrove A-LML-YSU buy dive - Aditech USA

This part provides the female portion of a YS mount at the end of your flex arm. It is the same mount that you find on an older Sea & Sea strobe. It will fit onto the YS male connector on the end of your existing flex arm. And allow you to connect another flex arm to your current flex arm. What? I can not think of any practical use for this piece except to extend a flex arm with a different brand of flex arm...
You also need to be careful about what type of flex arm you buy pieces for. I believe the L&M uses the real stuff (Loc-Line) while Fantasea and others use noncompatible bits. I can not tell from your picture, but I do not think your flex arm is Loc-Line.
From the image this looks like a FantaSea YS mount. Hence the arm is not loc-line. loc-line bits will not fit.Your lock line end cap is a fitting for a specific type of light I suspect. The light itself (looks like a BigBlue) has a 1" ball mount, which seems standard for that brand.
You could either buy a fitting to connect the lock line part to the ball mount, or remove the ball and attach a loc-line base to the light using a screw with the correct thread so you don't damage the threads on the light.
Here's a link to one of many available loc-line bases. 3/4
Note that the size of the loc line is important. There's small (about 1/2in) and large (3/4in). That end in your photo on the loc line will pop right off. You might also have to buy a line-to-line adapter like this

So IMO the easiest and cheapest route is to remove the ball and go loc-line all the way.
