A domestic appliance, such as a cyclonic vacuum cleaner (1), comprises a component, such as separating apparatus (3), carried by a chassis (2). A catch (11) is provided and is operable to release the component from the chassis. The component and the chassis are able to move slightly with respect to each other. When the appliance is lifted there is relative movement, against the force of resilient means, between the component and the chassis, so that the catch (11) occupies a position that inhibits its release. Previous proposals for catches inhibited from release when the appliance is lifted had a drawback in that slight relative movement between the component and the chassis when the appliance was resting on a surface tended to put the catch into the unreleasable position. For example, it was found that the action of grabbing the handle on the collecting chamber of a vacuum cleaner was sometimes sufficient to urge the catch into the locked position. The provision of resilient means provides some resistance to the catch moving into the locked position, thereby ensuring that the catch is inhibited from release only when the appliance is lifted from a surface.
