Abstract: A hair clip having a general "U" shape is provided with an arc segment on each of its two arms. The concave portions of the arc segments face one another. The arms are connected by a hinge portion. One of the arms is reinforced to control in which arm flexing occurs. The hair clip holds a generally cylindrical roller with its wound tress of hair in a direction generally perpendicular to the longitudinal axis of the cylindrical roller. The hair clip is adaptable to positively locate generally cylindrical rollers having a range of outside diameters.
