ABSTRACT:
A fitting is adapted to connect two hoses and includes first and second tubular members which include interconnecting end portions that enable the tubular members to be rotated relative to each other. The first tubular member includes a receiving end portion which receives an insert end portion of the second tubular member. An arrangement of flanges on the respective end portions of the tubular members defines cooperating grooves which receive a C-shaped retaining ring. When two hoses connected by the fitting are twisted relative to each other, the twisted hoses can be straightened by relative rotation of the first and second tubular members, thereby permitting smooth flow of fluid through the fitting.
