ABSTRACT:
A hose fixture device has a cylindrical wall with projections thereon, which projections engage a corresponding mounting projection of a hose. Normally that mounting projection is a helix, so that there is a screw engagement. The projections are arranged circumferentially around the cylindrical wall with gaps therebetween. There are also gripper members, again spaced circumferentially with gaps therebetween, which grip an end of the hose. The gaps make is easy to see such engagement. The gripper members are aligned with the gaps between those projections. This provides a secure fixing of the hose to the hose fixture device. Furthermore, the device may be moulded easily. Such a hose fixture device may be used to attache a hose joint component (e.g. a suction tool) to a hose of an electric vacuum cleaner.
