The permutation block comprises a locking slider normally biased for movement in a locking position, a control slider normally biased for movement in the locking direction and being manually controllable for movement in an opposite direction toward holding discs of a plurality of interlocking devices determining the unlocking code for the lock, a coupling member arranged between the locking slider and the control slider, the coupling member being shiftable transversely to the direction of movement of the sliders from a normal coupling position in which it transfers the movement of the control slider to the locking slider, to a holding position in which it decouples the control slider from the locking slider to allow the control slider to enter notches provided in the holding discs when the latter are aligned in a code setting position.
