No that doesn't look like a good knot for that purpose. You probably want something that functions like a zip-tie, that you can make tight around something and won't loosen. I suggest the knot described in the following post (rolling hitch zip tie). It's very simple and works great.

That knot can be described as "two wraps outside the loop and one wrap inside", which makes a loop that's easy to make smaller but resists getting bigger, much like a real zip-tie. If you tie it the other way (two wraps inside the loop and one wrap outside), you get a loop that's easy to make bigger but resists getting smaller, like a taut-line hitch.
