  • Patent number: 5356183
    Abstract: A coupling for a corrugated conduit has a body with a rotatable retaining ring. The ring has inwardly-projecting locking bars with two finger grips which project outwardly through slots in the body. When the finger grips are held and the ring is rotated, the locking bars are displaced inwardly to lie between adjacent corrugations of the conduit and retain it in the coupling.

  • Patent number: 5322329
    Abstract: The coupling for a vacuum fluid line has a tubular first coupling part (10) that can be axially inserted with radial play into an annular groove (14) in the frontal face of a bushing-shaped second coupling part (12) until it reaches a tight contact position and can be locked in this position. In order to facilitate and to be able to better control the release of the coupling, it is provided that on one of the coupling parts (10,12) a separation ring (24) is positioned in an axially fixed but rotatable manner. It has a cam-shaped lateral surface (34) that supports itself on a counter-surface (36) attached to another coupling part (10) and pushes apart the two coupling parts (10,12) by wedge action when the separation ring (24) is rotated.

  • Patent number: 5310225
    Abstract: A releasable connection made of plastic includes a sleeve-shaped central body having a first end connectable with a tube-shaped part and a second end axially receiving a junction piece having a circumferentially extending clamping rib. A rotatable clamping sleeve encircles the second end of the central body. The central body includes at least two radially deflectable resilient locking tabs with a cam surface on the interior of the clamping sleeve acting to selectively deflect the locking tabs radially inward to engage the junction piece. A first of the tabs is located to engage closely adjacent the clamping rib to prevent axial withdrawal of the junction piece and a second of the tabs is located at a position axially spaced from the first tab to radially position and stabilize the junction piece in the central body.
