Possibly. It depends where the splice is.
You'll need send an email to Jean-Luc on the simple loop, but I suspect it could be illegal. There is no issue with the handle.

Did the bury of the tail of the splice on the handle extend into the cleat ? (ie was the line thicker where it ran thru the cleat)
