Disclosed is an ornament including male-shaped ornaments which are attached to one surface of a desired portion, respectively; and a unit plate to fix the respective male-shaped ornaments to the other surface of the desired portion, so that the desired portion is freely flexible. A side of the male-shaped ornament is provided with a fitting protrusion which passes through the desired portion to fix the male-shaped ornament to the unit plate, and the unit plate is provided with an engaging hole into which the fitting protrusion is fitted. Also, disclosed are an ornament coupling apparatus and method for the ornament.

A fastening device and a fastening system including two fastening devices. The fastening device includes a first part having a first engaging side and a second part having a second engaging side, and at least two sets of individual engaging members configured to engage each other. Each set of engaging members includes a hook member and a locking member. The hook member protrudes from the first engaging side and has an engagement side from which a hook protrudes. The locking member is pivotably connected to the second part and extends into a recess in the second engaging side. The recess is adapted to receive the hook member for engagement with the locking member, and the locking member is configured to pivot towards the hook member when the hook member is in engagement with the locking member and a force is applied from the hook member on the locking member.

There is provided an apparatus for attaching an item to a substrate, using a prong ring with a ring and two or more prongs. When attached, the prongs extends from the ring on a first side of the substrate through such substrate and being bent. A lower die is positioned to approach the first side of the substrate. An upper die is on a second side of the substrate. The substrate is placed in a manner substantially perpendicular to the attaching movement of the upper and lower dies and a first redirecting member for redirecting the prongs which are bent inwardly. The first redirecting member cooperates with an abutting member positioned along the approach of the prong ring towards the first side of the substrate for inhibiting movement of the prong ring towards the substrate while the first redirecting member is used.
