1. A connecting device comprising a pipe nipple and a hose made of an elastic material and having a pre-existing recess on a circumference of the hose, wherein the hose rests against the pipe nipple in a sealing zone which at least over a part of a length thereof is surrounded by a hose reinforcement that forms part of a geometric positive-locking configuration for holding the pipe nipple and the hose together, wherein the hose reinforcement is connected with the hose in a positive-locking manner that does not rely only on friction, wherein the hose reinforcement engages in the sealing zone in the pre-existing recess on the circumference of the hose, and further comprising an elastic ring that engages in a grove in the pipe nipple and a groove in the hose reinforcement so as to hold the hose and the pipe nipple together in an axial direction, wherein the hose reinforcement has a stronger deformation resistance than the hose.
