An open ring-like device for holding articles such as plastic cards and keys is formed so that its ends are opposed to one another and includes tips at the ends. The distance between the tips is less than the thickness of an article. Articles can be inserted into the device by pushing the edge of an article against the tips to spread the tips apart. The article is slid in between the tips to fit a tip through a hole in the article to hold the article on the device. The device allows for the insertion or extraction of articles without a separate step of opening or closing the device.
