Abstract: A flexible board electrical connector includes a housing with two integral lower barb elements, and a front cover, which rotates on the housing between open and closed positions. Each of the lower barb elements has a vertical plate portion, and a lateral projection that extends laterally from an upper end of the vertical plate portion. When the cover is at the closed position, two retaining projections of the cover engage the lateral projections of the housing, thereby preventing upward removal of the retaining projections of the cover from the housing. The cover has two integral pivot pins on two end portions thereof, which are mounted respectively and rotatably within two accommodating spaces in the housing. Preferably, the housing further includes two integral upper barb elements, each of which has a horizontal plate portion, and a downward projection that extends downwardly from a front end of the horizontal plate portion into an inlet of a pivot accommodating space in the housing.
