ABSTRACT:
A tensile force actuated quick disconnecting coupling device for a fuel line having a vapor return has a pair of body members including interlocking elements which cooperatively couple and provide fuel and vapor passageways through the body members, and uncouple when a tensile force above a predetermined limit is interposed on the line. The interlocking elements are in the form of a mortise and tenon connection having a detent type infrangible locking member for interconnecting the elements together. The interlocking elements pivot one relative to the other so that a combination swivel joint and quick disconnecting coupling device is provided. Valving is disposed within each body member so that when the body members uncouple respective valves close the fuel passageways therein. The valving may include cylindrical stems which abut and open the fuel passageways when the body members are coupled and additionally permit pivoting of one body member relatively to the other. In one embodiment valving is also disposed with the vapor inlet passageway to close this passageway also when the body members uncouple, and this valving may include a cylindrical stem for abutting a portion of one of the fuel valves for opening the vapor passageway when the body members are uncoupled.
