Patent number: 6173994Abstract: A coupling assembly comprising a female connector body, a male member, a retainer and a dust barrier. The female connector body defines a bore extending axially inward into the connector body from an entrance. A radial face is defined in the bore axially inward of the entrance. The male member is received within said bore. The male member is formed at the end of a tube and includes a projection extending radially from the tube. The retainer has at least two locking beams extending between the radially extending projection and the radial face to retain the male member in the bore. The locking beams defines a slot between the locking beams. The dust barrier is slidably mounted on the tube. The dust barrier has at least one extension insertable within the slot so as to prevent inadvertent radially inward movement of the locking beams. Wherein upon sliding the dust barrier toward the female connector body, the dust barrier encloses the bore so as to prevent foreign material from entering the coupling assembly.Type: GrantFiled: November 29, 1999Date of Patent: January 16, 2001Assignee: TI Group Automotive Systems Corp.Inventor: Mark G.

Patent number: 6173998Abstract: A plug-in coupling connects two fluid conduits, one of which has a retaining rib. The plug-in coupling includes a sleeve having radial openings. The coupling also includes an arresting device displaceable within the sleeve. The arresting device has retaining arms. A free end of each arm is hook-shaped for engaging behind the retaining rib. Each of the free ends has an outer inclined face. When the sleeve and arresting device move apart, the inclined face presses against a front edge of the opening that receives the hook. When the arresting device and fluid conduit are pulled apart, an inner inclined face of the hook presses against the retaining rib. In an unlocking position, the outer inclined faces of the hooks are sufficiently spaced from the front edge of the respective opening so that the retaining arms may spread radially apart to permit decoupling. The arresting device also has resilient unlocking arms. An outer part of each one of the unlocking arms projects through one of the openings.Type: GrantFiled: July 16, 1999Date of Patent: January 16, 2001Assignee: Rasmussen GmbHInventor: Gerhard Bock
