Abstract
Abstract A fastener attachable to an article in an opening therein in which the fastener has two parts, an inner part and an outer part, with interengaging means permitting longitudinal adjustment of the over-all length of the fastener, grasping elements on each of these parts engaging the opposite side surfaces of the article when the fastener is in position in an opening in the article and a securing bolt extending from one surface of the article into the fastener and engaging the inner part as a nut with the bolt on rotation expanding the grasping elements of the inner part to engage the inner surface and drawing the parts toward each other to press the respective grasping elements of both parts into secure engagement with their respective surface areas on the article, the bolt being easily removable from the fastener so that the inner and outer parts may be removed as desired from their positions in the article opening.
