<p>The invention relates to a detachable fast-coupling which has an automatic assembly indicator and which is provided for connecting fluid lines, especially fuel lines used in the motor vehicle industry. The fast-coupling is comprised of a tubular insertion part (3) having a peripheral retaining rib (4) and of a receiving housing (1) having a cylindrical receiving space (6). Said coupling is also comprised of a separate retaining element (2) having retaining edges (10) which can elastically expand and which are provided for engaging behind the retaining rib (4) after the insertion part (3) has been inserted. An indicating part (8) is inserted in the insertion opening (7) of the receiving housing (1) in order to indicate a correctly executed assembly. Said indicating part is comprised of a support ring (9) having at least two retaining members (18) which are situated opposite one another, and which project inside the receiving space (6). Levers (19) which can pivot in a parallel manner in relation to the housing axis are formed onto the free ends of said retaining members. The levers (19) comprise stop projections (21) which project inward and which are situated on the ends thereof leading in the direction of insertion. The levers also comprise support projections (22) which are angled outward, which are situated on the ends thereof pointing toward the support ring (9), and which, when the indicating part (8) is installed, support in an axial direction on the inner facing wall (23) of the receiving space (6). By virtue of the inventive configuration of the indicating part (8), the stop projections (21), when the closed position is reached, are pressed outward by the retaining rib (4) of the insertion part (3) until the support projections (22) which pivot inward via the levers (19) detach from the inner facing wall (23) of the receiving space (6) and can advance outward through the insertion opening (7).</p> |
