I found one that looks like the ridged thing you have. Mine has a piece that slides in and out. I still don't know what it is but maybe that will help someone I.D. Yours. I just made it up in my head that it was an old travel razor handle. I found it next to a few disposable blade holders.
Ice Scratcher nailed the ID. It's a telephone drop wire clamp, the older ones are copper, the newer ones aluminum. I use 'em all the time on my telecom job.
