A piston-type safety lock device, of the type comprising a cylindrical rotor journalled in a cavity of a stator. Said rotor contains a plurality of radially slidable pistons cooperating at their inner end with the notches of a key for bringing their other end flush with the periphery of said rotor. Said other end bears against the inner surface of the cavity in which the rotor is journalled and, for one angular position of the rotor, against pistons slidable in the stator and elastically biased toward the rotor. Said pistons of the stator and rotor are flat blanked members. Said pistons are disposed respectively in a single slot of the stator and in a single slot of the rotor and have rectilinear and parallel lateral edges which are in contact with the lateral edge of an adjacent piston or the end of said slot.
