A method and device for charging a drill hole with explosives including a stocking of thin flexible material folded up to form a bellows with an axial duct closed at one end, a charging hose inserted into the duct on which the bellows slides, and a protecting sleeve at least partially enclosing the bellows so that upon charging of the hose the bellows is straightened out fold by fold and the bellows glides on the hose out of the drill hole.
