Injection device for filling hollow cavities in building and concrete walls with injectable material comprises a packer with a connecting piece for receiving a feed line for injectable materials; and a non-return valve. The valve seat is an inner cone (9) which is coaxially connected to a through-bore (4) and a rubber-elastic plunger (3) guided in a partial piece of the through-bore can be slid back through a ventilating connector up to the bulb (7). The connector has a pin which is flattened on both sides of its longitudinal axis. Preferred Features: The ventilating connector is made of high-grade steel.
