A disassembleable hinge comprising a fixed assembly susceptible of being associated to a frame; and a movable assembly susceptible of being associated to a door; the movable assembly being rotably mounted on said fixed assembly according to a rotation axis of the hinge; the fixed assembly comprising a pivot (A2) defining said rotation axis of the hinge, said movable assembly comprising two elements rotably mounted together according to a rotation axis (Y) of the movable assembly, said rotation axis (Y) of the movable assembly being parallel to said rotation axis (X) of said hinge; in each of said elements at least a seat (B2I, B2L) being obtained for said pivot (A2); said movable assembly presents at least a first and a second operating configuration; in said first operating configuration said elements (B, C) being rotated in such a way as to trap said pivot (A2); in said second operating configuration said elements (B, C) being rotated in such a way as to release said pivot (A2); the operating configuration of partial opening is realized through an intermediate opening system (10, 11, 12; 40, 41) susceptible of providing a sector of free stroke between the fixed assembly and the movable assembly.
