A snap hinge for supporting a closure element comprising a first articulated quadrilateral and a second articulated quadrilateral, sharing a first and a second lever having as a base element respectively a plate for coupling to a fixed element and a plate for fixing to a closure element, elastic elements acting between a point of the first lever and a point of the second lever and auxiliary elastic elements are arranged in series to the elastic elements and have opposite ends that are articulated to the first lever to a first pivot supported by a supporting element jointly associated with the fixing plate. The supporting element comprises at least one strip and one pair of first flaps formed so as to protrude from two opposite edges of the strip and provided with holes for the opposite ends of the first pivot. The strip is substantially inclined with respect to the plane of arrangement of the coupling plate.
