Abstract: A tubular socket for connecting a fluid conduit to a thermoplastic container has first and second thermoplastic parts connected to one another by a multi-component injection molding process. The first part has a smaller creep tendency under pressure load and a smaller swellability relative to hydrocarbon-containing fluids than the second part. The second part is fusion-welded to the container. The second part contains a reinforcement filler that is selected such that the creep tendency and swellability of the second part are approximately the same as that of the first part. A connection strength between the second part and the container is at least as high as that between first and second parts. A thermal shape stability of the second part is at least the same as the thermal shape stability of the container and at most approximately the same as the thermal shape stability of the first part.

Abstract: A hose clamp for clamping a hose on a pipe has a spring band bent to a ring-shape and end sections that positively lock one another in a locking position when the spring band is in a spread-apart position widened past a nominal diameter of a hose against a spring force of the spring band. The locking position of the end sections is releasable such that the spring band contracts about the hose. The end sections are positioned laterally adjacent to one another in an axial direction of the hose clamp and have a first edge and a second edge facing one another in the axial direction of the hose clamp. The first and second edges have at least one laterally projecting tooth, respectively.

Abstract: A coupling member for connecting a part, provided for receiving or dispensing fuel and made primarily of HDPE (high-density polyethylene), to a fluid line has first, second, and third components made of meltable material. The third component forms a heat fusion joint with the part for receiving or dispensing fuel and has an undesirably high permeability and swelling capacity relative to fuel. The third component is connected to the first component by material bonding and positive-locking action. The second component has greater fuel blocking capacity and higher strength than the third component. The second component is embedded in the third component. A volume ratio of second and third components is selected such that combined properties of the second and third components concerning permeability, strength, and volume changes by swelling are approximated to these same properties of the second component. The first and third components are heat-fusible to one another.

The heat conducting device is connected with a hose clamp for connecting the heat conducting device to the fluid line. The heat conducting device may include a metal strip, the one end of which is in contact with the heat source and the other end is connected to the clamp. This metal strip facilitates the heat transfer from the heat source through the clamp to the fluid line.

Abstract: A worm drive hose clip has a clamping strap with overlapping end sections, a clamping screw, and a housing. The radially outer end section has thread elements engaging the threaded screw shaft. The radially inner end section is connected to the housing bottom having a butt joint with interlocking undercuts. The bottom has a first transverse border with tongues arranged on opposite sides of the butt joint and projecting outwardly into an opening of the radially inner end section. A second straight transverse border of the bottom is supported on first grooves impressed radially inwardly in the clamping strap and opening toward the second transverse border. A second groove adjoins the opening and supports the bottom. The radially inner edges of the first and second circumferential grooves are aligned with an underside of the bottom and pass continuously into an inner side of the radially inner end section.

Abstract: Articulation sleeves for a clamp having strip ends formed into closed loops are surrounded by the loops. The head of a clamping screw, extending through slots in the loops and through the articulation sleeves is rotatably supported during clamping on one sleeve and a nut screwed onto the screw shaft is supported on a second sleeve and secured against rotation by a special shape of the sleeve. The sleeves have coaxial circular holes provided diametrically opposed one another.

The sleeve is compressed transversely to a longitudinal sleeve axis adjacent to the coaxial holes at least within an area of a polygonal peripheral nut contour and a peripheral screw head contour. The sleeve has a wall area deformed to match the polygonal peripheral nut contour.
