There. Is no thread !
You still need to turn it for a wire gland, no threads.As others have asked.... You sure those two holes aren't for a spanner wrench?
It might be a wire retained gland, is there a small notch on the side of the barrel near the top of the gland? If so does it have what looks like a square piece of metal in it? If so when you turn the gland enough in the correct direction the wire should "roll" out of the barrel releasing the gland which should just pull out.
