A connection device for a medical fluid conduit system,

• the connection device having a connection body which has a hose adapter and a connector piece for releasably fastening a further fluid conduit component or fluid storage component, the connection body being coaxially surrounded by a securing sleeve, and wherein in an operationally ready state a hose conduit is connected to the hose adapter,
• a hose portion of the hose conduit being plug-fitted in an adhesive-free manner onto the hose adapter, and the securing sleeve being axially securable on the connection body in two securing positions that are axially mutually spaced apart relative to a central longitudinal axis of the connection body, wherein rotatability of the securing sleeve relative to the hose portion is provided in a first securing position, and jamming of the securing sleeve on the hose portion that is plug-fitted onto the hose adapter is provided in a second securing position,
• wherein the connection body and the securing sleeve have mutually complementary profiled latching features which define the first and the second securing position of the securing sleeve on the connection body, wherein at least one profiled latching feature at least in portions is embodied so as to be resilient in a radially elastic manner in order for an audible latching of the profiled latching feature to be enabled in the first and/or the second securing position.
