Abstract
Abstract A two-part fastening device is provided for holding or attaching together one or more sheet-like articles and includes a gripping member having a base and firmly secured thereto a plurality of up-right, stiff, needle-shaped gripping elements which are adapted to pierce, penetrate, or pass through the sheet article to be held, and a receiving member cooperating with the gripping member adapted to permit the gripping elements to penetrate and lodge therein after penetrating the sheet article. Either part of the fastening device can also be provided with a secondary fastener such as a button, a zipper or self-gripping device. The fastening device is self-fastening and does not require a secondary process for attachment.
