Abstract: A universal joint for connecting ropes for use in fishing. Two U-rods connect two ropes together. The two U-rods are supported by a spindle so as to be rotatable relative to each other. At least one of the two U-rods is supported oscillatably by the spindle via a pin mounted detachably in a direction usually perpendicular to the axis of rotation of the spindle. When the connected two adjacent ropes are about to be twisted relative to each other, the two U-rods make relative rotation, absorbing possible twists. When the connected rope is bent, the U-rod swings to prevent the occurrence of excessive stress ascribable to the bend. The spindle or pin is provided with a retaining means for preventing the pin from slipping off.
