A lever arm is pin pivoted to the end of the wing, the lever arm being provided with a lug capable of engaging with the cylindrical spring, the lever arm being pivoted to the front portion of the spectacles pair, by means of a second pin. In this manner, the arms connected to the front portion of the spectacles pair are capable of being spread apart, by exercising a slight outwardly directed pressure.
