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.
