A spring toggle includes an outer wing, an inner wing, a spring and a bolt. The outer and inner wings each include a limb, a clipping flange and two sidewalls. The limb has a proximal end, a distal end and two edges. The clipping flange is formed on the proximal end of the limb. The sidewalls are formed respectively on the edges of the limb. The spring is mounted in the inner and outer wings. The bolt is inserted through the spring, extends between the clipping flanges of the inner and outer wings and has an outer thread. The outer thread of the bolt is clipped by the clipping flanges when the inner and outer wings are expanded by the spring.
