Connection device for media lines

A connection device for at least one media line that fluidly communicates a medium, the connection device comprising:

• a connection part having portions defining a socket, a line-side plug received within the socket and being circumferentially sealed therein, and a retention assembly locking the line-side plug in place whereby detachment of the line-side plug from the connection part is prevented, the retention assembly being located within the socket and including a clamping ring having a slit defined therein whereby the clamping ring is radially elastic, the clamping ring further including an outer conical surface and at least one inner toothed edge with non-positive and/or positive radial engagement with the line-side plug, the retention assembly further including an annular insert positioned with the socket and being axially moveable therein, the annular insert including an inner conical surface engaging the outer conical surface of the clamping ring, whereby the retention assembly is configured such that starting from a normal operating position the line-side plug can be moved over a specific travel path relative to the connection part in opposition to a return force (F) so as to enlarge an internal volume inside the connection part to which the medium is fluidly communicated, at least one seal provided for circumferentially sealing off the line-side plug and the seal being arranged inside the connection part in an area between the retention assembly and a spring element generating the return force (F).
