An anti-jamming strike plate (1) for locks (2) which comprises at least one laminar plate (3) provided with at least one seat (4, 5, 6) for at least one component chosen from between a spring latch and a sliding latch, and at least one space (7, 8) facing toward the lock (2) and defined on a jamb (9) of the installation doorway (10) of the door leaf (11) provided with the lock (2); the at least one laminar plate (3) surmounts the at least one space (7, 8); the at least one seat (4, 5, 6) of the laminar plate (3) has a shape and dimensions complementary to those of the corresponding component chosen from between a spring latch and a sliding latch, and the at least one space (7, 8) has larger dimensions than those of the corresponding component chosen from between a spring latch and a sliding latch; the at least one plate (3) is superimposed on the at least one space (7, 8) so that the at least one seat (4, 5, 6) is centered with respect thereto; at least one portion of the perimetric border of the at least one seat (4, 5, 6) comprises respective weaker portions (13) in order to allow respective deformations by the component chosen from between a spring latch and a sliding latch accommodated therein, in the event of structural settling of the installation doorway (10), with consequent free sliding of the component inside the deformed seat (4, 5, 6) and the space (7, 8).
