A clamping device suitable for securing a pair of flanges together is a unitary strip of a polymeric material that defines a multiplicity of clamping segments linked by flexible strip portions. The ends of the unitary strip define latching elements shaped to interconnect when the ends are brought together. Along one face of the unitary strip the clamping segments define teeth that project at opposite sides of the unitary strip, and these teeth define faces that are adapted in use to contact outer faces of the pair of flanges. Each clamping segments may define two opposing teeth. The clamping device can be operated with a single hand, being bent around the outside of the pair of flanges so that the clamping segments engage opposite faces of the pair of flanges and hold them together, and the latching elements are interconnected.

A valve connector includes a housing and a pressing device. The housing includes an operative end, a coupling end, and a through-hole extending from the operative end through the coupling end. The pressing device includes a push seat received in the through-hole and located between the lever and the coupling end and a lever abutting against the push seat and pivotably connected to the housing. The push seat includes a first passageway. The lever includes a second passageway and is operable to move the push seat. When the lever is in a release position, the first passageway does not intercommunicate with the second passageway. When the lever moves from the release position to a locking position, the push seat moves towards the coupling end, and the first passageway intercommunicates with the second passageway when the lever is in the locking position.

A method and apparatus for an improved safety cam lock fitting having ergonomically designed double cam levers having outer and inner portions so that when the outer cam levers are opened and the inner cam lever remain closed, the male and female portions of the cam lock fitting only slightly separate from each other allowing the operator to quickly reclose the cam lock fitting if the operator observes that the cam lock fitting still contains pressurized material. This is accomplished by providing a larger cam lobe on the outer cam lever and a smaller cam lobe on the inner cam lever so that when the smaller cam lobe is in a closed position and protrudes into a peripheral groove on the male portion the male and female ends have a small space therein between. Various configurations of the cam portions relative to each other are provided. Various lever locking assemblies may be used to prevent the cam levers from being inadvertently opened.
