Abstract:
Plug connector for releasable connection of a pressurized line (2), comprising:a housing body (4) with a receiving opening (6) for insertion of one end (2a) of the line (2), and with an inner sleeve (8) attached in housing body (4) in an arrangement extending coaxially within the receiving opening (6) for engagement into the inserted line end (2a), in which a clamping element (12) is mounted to move axially in the receiving opening (6), so that the clamping element cooperates with an inner conical surface (14) of the housing body (4) to secure the line (2) and, in so doing, acts radially inward against the outer periphery of line (2) with at least one mounting edge (16) in shape-matched or frictional and shape-matched fashion;the inner sleeve (8) being rigidly attached media-tight around the periphery in housing body (4) via connecting devices (20) and engaging media-tight around the periphery in the line (2) with sealing devices (22);the connection devices (20) comprising an annular collar (26) of the housing body (4) extending radially inward and a mounting section (30) of the inner sleeve (8) tightly attached in an opening (28) of the annular collar (26); andthe mounting section (30) of the inner sleeve (8) being tightly attached in bonded fashion in the opening (28) of the annular collar (26).
