Abstract
A fastener comprises two engagement springs on opposite sides of the fastener. Each engagement spring has an elongated rib. The elongated ribs may have a substantially rectangular shape, or any suitable shape, and they may protrude away from the opposite side of the fastener. Additionally, the elongated ribs may have same or different slopes at each end of the ribs. According to one embodiment, the elongated rib increases the removal to insertion force ratio as compared to such ratio when the engagement springs do not have the elongated rib.
