Connection element for a composite hose and process for connecting composite hose

A process for connecting a composite hose having a spiral wound metal hose encased by an elastic outer casing, comprising the following process steps:

• Setting an end of the composite hose to be connected on a supporting sleeve having an outer thread adapted to the metal hose so that the outer thread engages into spiraled depressions on an inner wall of the metal hose;
• Screwing the wound metal hose onto the outer thread of the supporting sleeve;
• Fastening the composite hose on the supporting sleeve by radial pressure;
• wherein,
• Following screwing the wound metal hose onto the outer thread of the supporting sleeve, a portion of the wound metal hose is compressed axially such that the outer casing is exposed projecting beyond the end of the metal hose and comes to lie on an annular sealing surface of the supporting sleeve axially bordering on the outer thread and spaced from the outer thread by a shoulder, the annular sealing surface being adapted to receive the exposed projecting outer casing;
• and
• The exposed projecting outer casing of the composite hose is pressed exclusively on the sealing surface so as to be radially sealed therewith.
