Abstract: A device for supporting a wire on a post, having a body with a base portion and two arm portions which extend away from the base portion generally in the same direction. A wire receiving opening is formed between the two arm portions. To use the device, it is affixed to a post at one arm portion and with the opening upwardly open. The wire to be supported is then inserted into the opening, between the arm portions, after which the arm portion which is not affixed to the post is deformed inwardly towards the post to substantially close the opening around the wire so that the wire is captured by the device.
