<p>The system has a conical ring (6) mounted to a housing (8) during assembling of a fitting. A signet ring (1) overlaps the conical ring and the housing from outside and holds the conical ring and the housing together. The ring (1) overlaps at ring surfaces (7, 9), which are locked with each other. The ring (1) has hook-shaped inner projections at an axial border area, where the projections run in a circumferential/peripheral direction and engage in complementary recesses at an outer circumference of the conical ring and the housing. The rings and the housing are made of plastic material.</p> |
