Patent number: 11199285Abstract: A plug-type connector for media lines having a coupling part into which a plug part can be inserted. The plug part can be retainingly engaged in the coupling part by a retaining clip that has at least two pairs of spring arms. The clip can be premounted on the coupling part by latching of the spring arms. The clip is U-shaped wherein legs of the U-shape form the two pairs of spring arms, which pairs are arranged one behind the other in the longitudinal direction and are separated by a slot and are elastic in the radial and axial directions. The first pair of the spring arms interlockingly blocks the plug part against being pulling out of the coupling part, and the second pair of spring arms holds the retaining clip captively in the coupling part in pre-assembly and assembly positions.Type: GrantFiled: October 19, 2016Date of Patent: December 14, 2021Assignee: VOSS Automotive GmbHInventors: Jochem-Andreas Hess, Eugen Heinrichs, Alexander Oberdörfer, Sascha Rosenfeldt, Lukas Röhrig
