A fastener comprised of a base having tongue-shaped strips, an adhesive layer attached to the base and covered with a detachable sheet or at least one synthetic resin sheet. To utilize the fastener, the detachable sheet is stripped from the adhesive layer, or the synthetic resin sheet is melted, securing the base to the attaching surface of a file etc. by the bonding force of the adhesive layer or by the heat-welding of the synthetic resin sheet. In alternate embodiment the base and tongue-shaped strips are encapsulated between two synthetic sheets with the adhesive surface being on one of the sheets. Detachable release sheet is applied to the adhesive layer until ready for use.
