Abstract
A closure casing has two co-operating closure members defining an enclosed space between them when in a juxtaposed closed position. A clamp is provided that holds the closure members together in the closed position, the clamp includes at least one over-center or toggle clamp mechanism, one part of which passes through openings in the closure members which are aligned when the closure members are in the closed position, to engage a face of the closure member remote from a second part of the toggle clamp mechanism. The second part is turnable between a clamped position and a release position. At least one of the closure members has a resilient element engageable by a third part of the toggle clamp mechanism and operable to apply a resilient resistance to the clamping movement to hold the clamp mechanism in the clamped position.
