  • Patent number: 5464179
    Abstract: The invention concerns a two-piece holding assembly made of plastic for mounting of at least one tube-shaped part such as a vehicle fuel line or the like. The assembly includes an outer dish element 2 of hard plastic material which is attachable to a support via a mounting zone. An inner dish-like element 3 formed of soft plastic material and having at least one storage location 5 for acceptance of the tube-shaped part is received in outer dish element 2. In the preferred arrangement, the inner dish-like element 3 is attached on both sides of storage location 5 via an anchorage 6, 6' to the outer dish-like element 2. Between inner dish-like element 3 and outer dish-like element 2 in the area about the storage location 5, there exists an open transverse free space 7.

  • Patent number: 5447337
    Abstract: A tube-type coupling or clamping joint is formed of plastic and comprises two cylindrical cartridge-shaped body portions 2, 3 having end regions 8, 9 which interfittingly overlap and mate with each other in a detachably connected manner. At least one locking part 10 is arranged for joining the elements 2, 3. One end region of one of the cartridge-shaped elements carries at its outer circumference at least two stop elements 11, 11' which extend at right angles to the longitudinal axis L--L. Axially behind the stops 11, 11' there is arranged to be inserted as a portion of the locking part 10 a stop arm 12, 12' that can rotate at right angles vis-a-vis the longitudinal axis of the coupling. Located in the other end region 9 of the mating cartridge-shaped element is a resilient ring element 14 and a locating flange 16.

  • Patent number: 5316245
    Abstract: The subject invention relates to a holding element made of plastic, with a first part (2) formed of hard plastic and having a storage zone (5) for acceptance of at least one tube-shaped part. A second part (3) made of soft, attenuating material is embedded in the first part (2) and a third part (4), embedded in same via a traversing aperture (6) exhibiting a holding zone (7"). According to the invention, the holding zone (7") of the third part (4") may be designed as a peg (23), equipped with at least one profiling (22) positionable into the aperture of a support, or as an arrow base (40), or as a spreader rivet (50).

  • 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.

  • Patent number: 5170984
    Abstract: The invention concerns a holding element 1 made of plastic and having at least one storage or gripping zone 5 designed for receiving and holding at least one tube-shaped part adjacent to a mounting zone 7. The holding element 1 is characterized by a three-component design which includes a first component 2 made of a hard plastic material and carrying the storage or gripping zone 5. A second component 3 formed of a soft plastic vibration damping material is positioned in component 2 and receives a third component 4 formed of hard material which is positioned in component 3 via a transverse aperture 6. Component 3 carries the mounting zone 7 which provides the ability to connect the holding element to an associated support structure.
