Abstract:
The invention relates to an end hose for discharge of thick substances, particularly of liquid concrete. The end hose (12) can be connected with its entry-side end to a pressure feed line (14) of a mobile thick-matter pump, and has a discharge opening (16) for the thick substances at its exit-side end, and consists of a flexible material. In order to prevent the end hose (12) from kicking out when blockages are loosened, it has at least two hose parts (26, 28) having different bending rigidity, connected with one another at a transition point (30).
