An anti-intrusion cylinder (1) for locks of the type comprising a stator (2) which is provided with a substantially cylindrical longitudinal cavity (3) for accommodating a rotor (4) with a longitudinal seat (5) for the insertion of a key (6); the rotor (4) and the stator (2) comprise a plurality of channels (7), which are substantially aligned and facing when the cylinder (1 ) is in the locked configuration; such channels (7) accommodate respective pins (8), counterpins (9) and optional elastic means (7a) which are adapted to prevent the rotation of the rotor (4) in the stator (2) in the absence of the key (6) from the longitudinal seat (5). According to the invention, at least one of the pins (8) comprises a shank (10); such shank (10) is provided with a mushroom-shaped terminal (11) with a diameter smaller than the diameter of the shank ( 10); the terminal (11) is faced toward and proximate to the corresponding counterpin (9); at least one contoured annular body (13) has a substantially similar diameter to the diameter of the channel (7) and is fitted, with mechanical play, over the mushroom-shaped terminal (11).
