Abstract
A spring fastener, which comprises two engagement springs in opposite sides of the fastener. Each engagement spring has an engagement portion comprising a hindrance portion, which increases considerably the removal to insertion force ratio as compared to such ratio when the engagement portion does not have the hindrance portion, thus permitting very easy insertion into, with considerably more difficult removal of the fastener from the slot of a panel.
