ABSTRACT:
A telecommunications closure (1) includes a pressure clamp (21) for sealingly clamping mating parts (47, 48) of the closure together so as to form a water tight seal. The clamp member requires no tools during installation and creates no uncertainty as to the generation of appropriate clamp pressure on a sealing O-ring when installed. The pressure clamp includes an over-center latch which is rotatable between a first unlatched position and a second latched position, a clamping pressure generated by the latch increasing to a maximum value as the rotatable latch is moved from its first position to an intermediate position between the first and second positions and then decreases from this maximum value as the latch is moved from the intermediate position to the second position so as to generate a predetermined appropriate clamping pressure when in its second position so as to appropriately compress the O-ring disposed within a groove between the closure parts at their mating area.
