An injection device comprises an injection pipe (1) having front and rear ends (2, 3). There is an elastic, expandable ring (6) on the outside of the pipe (1) for fixing and sealing the same in a bore hole. At a point at a distance from the rear end (3) of the injection pipe, a branch pipe (13) is connected which may be connected to a hose (12) for supplying mortar or water to the interior of the injection pipe. In a rear gable piece (16), a piston (18) being movable to and fro is arranged which may be connected to an external percussion mechanism with the purpose of setting the mortar or the compound inside the injection pipe in vibration. During injection, the mortar is fed into the bore hole under low pressure.
