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.

A combined quick connector structure for fuel feed and return system may include a cover assembly; a lever mechanism along the inside walls of the fuel feed and fuel return openings of the cover assembly; a pawl and ratchet mechanism on either side of the cover assembly; a rib on either side of a connector assembly; the connector assembly with retainer elements for engine feed and engine return lines and fuel feed and return lines; actuator pads provided on the external and internal circumference of the openings of connector assembly; a locking mechanism on the inside circumference of the retainer elements for the fuel feed line and fuel return line; and a lever mechanism configured for hinging the cover assembly together with the connector assembly.

A coupling/uncoupling device for a plate-like multi-coupling device for the simultaneous connection of a plurality of hydraulic, electrical, and/or pneumatic lines includes quick couplings. In particular, the coupling/uncoupling device is provided with a safety device configured to prevent an accidental uncoupling and to be operated by the operator with one hand only. A plate-like multi-coupling device the includes such coupling/uncoupling device is also an object of the present invention.

A ratchet clamp with automatic fail safe preferably includes a first clamp half, a second clamp half, a ratchet arm and a locking ratchet device. The first and second clamp halves include a substantially semi-circular shape and a V-shaped cross section. One end of the first clamp half is pivotal secured to one end of the second clamp half. The ratchet arm includes a plurality of teeth. The locking ratchet device includes a ratchet lever and a lock pawl. The ratchet arm extends from an opposing end of the first clamp half. The locking ratchet device extends from an opposing end of the second clamp half. The ratchet arm is inserted into the locking ratchet device. The ratchet lever is lifted to tighten the clamp around flanges of two pipes. The lock pawl is used to lock a position of the ratchet arm relative to the locking ratchet device.

A nozzle adapter for connecting corrugated tubing to a fog nozzle housing. The nozzle adapter comprises a channel body and a clamp, the channel body having a connector section and defining a flow channel extending through the channel body. The connector section comprises an outlet opening of the flow channel and is adapted and configured to removably connect to a piece of corrugated tubing. The clamp is operatively connected to the channel body and operable to clamp a fog nozzle housing so that an outlet end of the fog nozzle housing faces downstream toward the flow channel.

A hose connector apparatus for quick and easy dripless hose connection includes a first connector having a first inner end, a first outer end, and a first sidewall. The first outer end attaches to a first hose. The first inner end has a receiving cavity. A male clamp bracket is pivotably coupled to the first sidewall. A female clamp bracket is pivotably coupled to the male clamp bracket and has a female bracket distal end. A second connector has a second inner end, a second outer end, and a second sidewall. The second inner end has a protrusion portion slidably engageable within the receiving cavity of the first connector. The second outer end attaches to a second hose. A pair of locking pins is coupled to the second sidewall to selectively engage the female bracket distal end of the female clamp bracket.

Disclosed is a ball joint for connecting two floating pipes, the joint including an inner shell part, an outer shell part and a clamp with segments that are moveable in a common plane between an open position in which at least one of the shell parts is moveable into and out of the clamp, and a clamping position in which movement of both shell parts along the longitudinal centre lines is prevented. The ball joint is provided with a remote controlled actuator for driving movement of the segments between the open and closed position, without requiring nearby personnel to keep the shell parts aligned. Also disclosed is such a clamp and to a method of connecting such a ball joint to two pipes.
