A locking device for a roll-up blind, gate or door having slats rollable up and down on a shaft, the slats being slidable inside lateral guides, a first of the slats being attached to the shaft and a last slat adapted to rest upon an outer windowsill. The improvement is directed to the fact that at least one of the slats includes along its length a recess for receiving a pivotally movable catch, the catch including a foot, the foot being positioned inside a groove of an open cavity that opens toward the window, of a recess that is provided in the slat profile, the catch, adapted for insertion into the cavity of the recess, including a foot, the foot being offset relative to a centre of gravity of the catch, the foot having a profile capable of sliding inside the groove, whereby the catch can flip out freely when the end slat comes to rest upon the outer windowsill; and blocking means associated with one of the lateral guides for interacting with the catch when the roll-up blind, gate or door is moved upwards.
