ABSTRACT:
A connecting device for sealingly connecting together a pair of modular compressed air conditioning units, for example a filter and a lubricator, comprises a generally rectangular clamp adapted to engage a pair of ported flanges formed respectively on the units to be connected so as to urge the units into fluid-tight communication with one another via an intermediate ported spacer retaining O-ring seals. One side of the rectangular clamp is pivotally mounted so that it can be pivoted out of its operative position to permit reception of the flanges into the clamp and then pivoted back into its operative position in which it can be releasably locked by tightening a bolt. The device may be unitary in nature, i.e. has no separate parts that might otherwise get lost, and is simple to manufacture and manipulate.
