摘要： A spring-loaded coupling device for releasably interconnecting confronting ends of first and second fluid carrying conduits is provided. A pair of symmetrical arcuate coupling halves are pivotally jointed together at first adjacent ends for circumferentially surrounding the conduit ends. A latch is mounted adjacent the opposite end of one of the halves. This latch includes a flange having a slot opening outwardly and an outwardly extending flat spring lock terminating in an end surface. A toggle is provided which has a first end pivotally mounted adjacent the opposite end of the other of the halves, and has a second end extendable longitudinally beyond the opposite end of the first of the halves. The toggle includes a locking pin adjacent the second end of the toggle and engageable with the slot when the coupling halves are closed around the sleeve and has a spring urging the toggle to pivot in a direction to move the locking pin into the slot. A cam is provided for rotating the toggle against the force of the leaf spring as the coupling halves are closed to cause the locking pin to clear the flange and drop into the slot to form a primary lock. An aperture adjacent the second end of the toggle receives the spring lock which snaps into locked position to form a secondary lock. The coupling may have spherical shoulders to reduce localized stresses and forces.
