A canister vacuum cleaner comprises a main body 11, a hose 12, and a coupling 13 for attaching the hose 12 to the main body 11. The coupling 13 comprises a first part 16 attached to the main body 11 and a second part 17 attached to the hose 12. Each part 16, 17 is a duct through which fluid is carried from the hose 12 to the main body 11. The second part 17 is attachable to the first part 16 by sliding the second part 17 relative to the first part 16 along a sliding axis (52, fig 7). When the second part 17 is attached to the first part 16, the two ducts seal in a sealing plane (53, fig 7) that is non orthogonal relative to the sliding axis (52, fig 7). The sealing plane (53, fig 7) is preferably non-parallel relative to the sliding axis (52, fig 7) while the sliding axis (52, fig 7) is preferably parallel to the longitudinal axis of the hose 12. The coupling may include a bend which preferably occurs in the second part 17. |
