Fixing ring, and assembly of a hose and fixing ring

An arrangement comprising:

• a hose (2);
• a connector (10) having a nozzle (9) with a conical end (46);
• and
• a fixing ring (1),
• wherein the connector (10) can be arranged in the hose (2) and the fixing ring (1) can be screwed onto the hose (2) in such a way that an outside (3) of the fixing ring is freely accessible and an inside (4) of the fixing ring is in contact with the hose (2),
• wherein the inside (4) comprises a cylindrically shaped internal thread (5),
• wherein the fixing ring (1) comprises a holder (6) formed by a conically tapering end (40) outside the threaded region, the holder (6) having an inner diameter (7) smaller than the inner diameter (8) of the internal thread (5),
• wherein a circumferential elevation (41) is arranged in the conically tapering end (40), the circumferential elevation (41) comprising a ramp (43) on one side in extension direction (42) of the hose (2) and a circumferential edge (45) at the radially inner end of the ramp (43),
• wherein the internal thread (5) is adapted to press the hose (2), which has been pushed onto the connector (10), against the connector (10) and, by pressing the thread (5) into the outside of the hose (2), to press the hose (2) against the connector (10), at least over a partial section of the connector (10),
• wherein the elevation (41) is designed such that, in addition to the thread (5), also the edge (45) is pressed into the outside of the hose (2), to press the hose (2) against the conical end (46) of the nozzle (9) of the connector (10);
• and
• wherein the outside (12) of the hose (2) is produced from a softer material (14) than the internal thread (5) of the fixing ring (1), and the hose (2) comprises a threadless surface (13).
