A fastener, which consists of a head (3), a connecting piece (4), a horizontal bar (5) and a neck (6), is assembled by a bar (7). Fasteners of the first fastener assembly member (1) are joined with the second fastener assembly (1') in a straight line. The clearance between the fasteners can not be smaller than the thickness of a fastener. The contact planes (8, 8') of the fastener assembly members are stuck together. The shape of the contact plane can be varied. |
