Patent attributes
A device for sealingly linking two end pieces (24) of a fluid line system, comprises a casing part (1) and an inner part (13). The inner part (13) is arranged in a prefabricated arrangement within the casing part (1) in an axially displaceable manner and serves to fixate a sealing unit (21) that is detachably linked with the inner part (13) until an end piece (25) is inserted into the casing part (1) via an introduction area (3) and comes into contact with the inner part (13). When the end piece (25) is inserted, the inner part (13) is axially expelled from the casing part (1), whereby the sealing unit (21) is inhibited in its axial movement by an abutment (12) and remains within the casing part (1). The two end pieces can be sealingly linked while indicating the relative position of the end piece (25) coming into contact with the inner part (13) without requiring a separate handling of the sealing unit (21).
