ABSTRACT:
The clamp comprises a strip of heat-settable plastic which has two spaced, parallel strip magnets secured on one surface thereof, and which is bent into generally U-shaped configuration, for example by directing a heat Knife onto the plastic strip medially of the space between said magnets, while folding opposite ends of the strip toward each other until the two magnets are placed in registering engagement with each other. After the plastic strip has been folded it is cooled to heat set the radiused fold, which thereby helps to retain the clamp closed and the magnets in engagement with each other.
