ABSTRACT:
A safety clamp system for securing the lever arms of a quick connect coupling to prevent the accidental movement of the arms which would cause a failure of the coupling mechanism for two coupling pipes. Once the pipes have been joined by a standard quick connect coupling, the clamp of the present invention is positioned to encircle the lever arms and hold them down secure against the body of the coupling. The safety clamp is separate from the coupling mechanism and is itself not an aid in the joining of the pipes. The clamp arms encircle approximately 270 degrees of the pipes circumference, making contact only at a few points about the coupling's periphery, some of the contact being flat, face-to-face surface area engagement with some "L" shaped hooking, and utilizes a resilient spring biasing hooking mechanism to prevent the separate, pipe coupling mechanism from accidently becoming undone but allowing relatively easily disengagement of the clamp from the coupling when so desired.
