ABSTRACT:
The connecting element for transporting gaseous, liquid or solid substances include a tubular coupling which has on the inside a cylindrically running first recess, in which a corrugated tube is arranged, and which has a cylindrically running second recess which adjoins the first recess and In which an annular seal is arranged adjacent to the first recess and an expanding ring is arranged adjacent to the annular seal. The expanding ring has, on the outside, a first projection which points toward the coupling and engages in an encircling groove arranged in the second recess. With its projection which points toward the corrugated tube, both the expanding ring and the annular seal are in each case in engagement with the corrugated tube from outside. The subject matter of the invention is also the use of the connecting element as a subassembly in windshield washer units.
