ABSTRACT:
A tensile force actuated fuel line quick disconnecting coupling device has a pair of body members including interlocking elements which cooperatively couple and provide a fuel passageway through the body members, and uncouple when a tensile force above a predetermined limit is interposed on the fuel line. The interlocking elements may be in the form of a mortise and tenon connection having a detent type infrangible locking member for interconnecting the elements together. The interlocking elements may pivot one relative to the other so that a combination swivel joint and quick disconnecting coupling device is provided. Various types of interlocking members are disclosed as are both infrangible and frangible locking means. Valving is disposed within each body member so that when the body members uncouple respective valves close the flow passageways therein. The valving may include cylindrical stems which abut and open the passageways when the body members are coupled and additionally permit pivoting of one body member relatively to the other.
