Patent number: 7025387Abstract: The connection device (101, 201) according to the invention has a locking head (109, 209) that can be locked to an opening (8) of a container wall (3). A clamping device (123, 223) is also provided on the corresponding coupling piece (5), which serves to tighten the head (109, 209) locked to the container wall (3) without a rotational movement against the container wall (3). The clamping device (123, 223) can be designed as a wedge-clamping device (142, 242). The latter permits generation of large clamping forces with small operating forces. The clamping device (142, 242) is preferably secured by a locking device (253), so that vibration-proof connection resistant to temperature changes is achieved during simple assembly.Type: GrantFiled: January 8, 2002Date of Patent: April 11, 2006Assignee: Eaton Fluid Power GmbHInventors: Harald Twardawski, Thomas Luft, Bernd Halbrock, Michael Markus Huck

Publication number: 20040093726Abstract: A plug-in line connector (1) for especially simple and secure assembly has a fluid-tight plug-in connection and a locking device (25), which is very easy to access when its retaining parts are assembled in the axial direction and which is locked so that it cannot be released by passing a locking point. A tension spring, which is formed as a ring and acts as a block, is used for the locking element. This guarantees particularly low activation forces and minimizes axial play.Type: ApplicationFiled: November 24, 2003Publication date: May 20, 2004Inventors: Michael Markus Huck, Bernd Halbrock, Thomas Luft, Harald Twardawski
