Abstract
Abstract A hair clip includes a base plate, a spring board and a retainer, the base plate pivotally supporting the retainer at one end, wherein the spring board is placed between the base plate and the retainer such that the spring board is stopped from extending lengthwise at both ends, whereby, when the retainer is latched to the free end of the base plate, the spring board is compressed lengthwise thereby to bend toward the base plate while holding the user's hairs against it.
