Abstract
Apparatus is provided comprising non-magnetic male and female coupling sections having reciprocally mating interrupted screw portions. The male section has a permanent magnet disposed in a first cylindrical chamber in the mating end thereof. The female section has a movable magnetic plunger captively disposed in a second cylindrical chamber in the mating end thereof which is free to enter the first chamber when the male and female sections are properly aligned and the interrupted screw portions are locked. Magnetic attraction holds the plunger in the first chamber. The male and female sections are thus precluded from further rotation relative to one another. A strong external magnet is used to withdraw the plunger from the first chamber thus allowing rotation and demating of the male and female sections.
