Abstract
An improvement in an accessory for a garden hose and the like in which an end of the hose is to be connected with a supplementary fitting characterized by a centerpiece adapted to sealingly receive the end of the hose, a gripper for moving longitudinally into gripping relationship with the hose, a turnbuckle for drawing the gripper into gripping relationship with the hose responsive to relative rotational movement of the turnbuckle with respect to the gripper and rotation prevention means to prevent relative rotational movement between the gripper and the centerpiece. Also disclosed are preferred structures and embodiments in which, for example, a whole coupling has mirror image type centerpieces, grippers, turnbuckles, and rotation prevention means; dual slope inverted frusto conical sections; right hand and left hand threads for effecting the longitudinal movement of the grippers; the multiple-piece structure of the turnbuckle insert; the tangs on the grippers engaging slot means on the centerpiece to prevent relative rotation; the retention structure on the tangs limiting axial travel of the grippers; and the removable inverted frusto conical sections of the centerpiece.
