There is disclosed a quick acting coupling for interconnecting tubular members such as hoses which is particularly useful with fire fighting equipment. The device has a body member for attachment to one of a pair of tubular members. The body member distally carries a plurality of segmented jaws which are pivotally mounted thereon to permit movement between radially expanded and contracted positions. The outer surfaces of the jaws have flat grooves having leading and trailing cam surfaces. The jaws are surrounded by a cam guide ring that is mounted for limited axial displacement on the assembly of jaws with cam guides of mating contour. The cam guide surfaces are beveled, planar surfaces and are engaged by the cam guides of the cam ring in both the opened and closed positions so that axial movement of the cam ring positively expands and contracts the segmented jaws. |
