Abstract
A coiled latch for locating and holding a filter in a housing has two coaxially disposed turns preferably in the form of a conical helix, the smaller of the turns exerts a force on the filter holding it into the housing, while the larger of the turns abuts the peripheral margin of the filter to center it in the housing.
