Abstract: A device and method for coupling two or more objects together has a coupling that has at least two magnets or metal pieces and is removably attached to a first object. A second object has at least two corresponding metal pieces or magnets, wherein the first object and the second object are held together by magnetically attractive forces when the first object and the second object are engaged.

Abstract: An article and method for coupling two or more objects together uses magnetically attractive forces generated by corresponding magnet(s) and/or metal piece(s) positioned at or near the periphery of the two or more objects. Multiple magnet(s) and/or metal piece(s) are spaced-apart around the periphery of the two or more objects. Alternatively, two corresponding annular magnet(s) and/or pieces of metal are used. Where multiple spaced-apart magnet(s) and/or metal piece(s) are used, the magnet(s) and/or metal piece(s) are either regularly spaced-apart or asymmetrically spaced. The coupling device is generally designed to hold tubular objects together. The coupling device has numerous advantages, including, for example, rapid assembly and disassembly, pressure release characteristics, superior ergonomics for the user, increased adjustability for specific applications, and improved durability.

Abstract: A method of coupling the upper and lower section of a humidifier container used to humidify oxygen gas, using magnetic coupling means. A series of corresponding magnets around the container, located externally to the device or internally, secure the lower part or vessel to the upper part or cap. Using magnets opposing an attracted metal may he used in lieu of corresponding magnet to magnet attraction which requires the poles of the magnets be oriented with their poles to attract each other.
