ABSTRACT:
Plug connection between a corrugated hose and an unprofiled pipe. A plug connection is provided between a corrugated hose (1) and an unprofiled pipe (31), a holding element (3, 34, 50) that surrounds the unprofiled pipe (31) being connected at least indirectly with the hose end (4), and the end (31) of the unprofiled pipe being surrounded by a sealing ring (16, 17, 30) that is situated before the holding element (3, 34, 50). The sealing ring is connected at least indirectly with the hose (1) so as to form a seal. It is provided that the holding element (3, 34, 50) is situated in the hose end (4) and is held thereby, at least indirectly, by mutual positively locking engagement in the axial direction, and that on the other side of the seal (17, 18, 30) a guide sleeve (18, 25) having an inner diameter that corresponds to the outer diameter of the unprofiled pipe (31) is situated before the holding element (3, 34, 50). The sleeve is held radially by the hose (1) practically play-free, and at least indirectly, by mutual positively locking engagement in the axial direction.
