A spring lever is provided on the common pivot of the guiding part of the double arm and the link member which is mounted between the ends of the two ends of the guiding part and is connected at one end therein to the fixing part on the frame as well as pivotally engages the fixing part on the leaf at the other end by means of an intermediate link. The lever coacts with a snap action by means of its free end portion with the mounting pivot of the intermediate link in the closed position of the hinge. Such a construction enables a normal double-armed hinge to be easily converted to a spring hinge.
