@TheAmmoniacal,
As you likely already know, PM8918 probes and accessories are not only hard to find but horendously expensive

I own a lot of PM8918 probes and accessories and will take a look to see if there is a spare probe clip amongst them. I will let you know.
I also have a complete, virtually new, in the box, Philips PM97 scopemeter with all probes. That will likely raise around £200 on ebay when I sell it, but the daft thing is that the two PM8918 probes that it comes with sell for almost as much on their own. its a mad mad world
