A hair securing means, such as a hair-clasp or barrette, or a hair-comb, which comprise a pivotal resilient locking lever, and a locking pin provided with a panlike recess having two surfaces which are inclined at an angle to each other. The locking lever cooperates with the locking pin by engaging the panlike recess. The locking pin has a head in the shape of the surface of the circumference of a circular cylinder. The longitudinal axis of the latter is the apex line of the panlike recess. The surface of the latter extends at least to one half of the circular circumference. The locking lever is provided with a rectangular opening, and the length of the opening corresponds to the width of the head and the width of the opening corresponds to the thickness of the head plus an amount less than the depth of the recess.
