An adjustable locking hinge for holding a door either completely or partially open. The adjustable locking hinge has an adjustable friction resistance and allows retention of the door at any desired angle. The hinge includes two hinge leaves with knuckles in an intermeshing relationship with each other, and a hinge pin that extends through the knuckles that is axially shiftable to locked and unlocked positions. Two pins extend upwardly from opposite sides of a base element and engage a sprocket plate mounted on the hinge pin, in the locked position. In the locked position, the resistance to move the door is adjusted by an actuating mechanism. A protective cap is removably attached to the base element, and covers the components of the locking mechanism. The protective cap has a central aperture through which the top portion of the actuating mechanism extends. The lower portion of the hinge pin includes an axial bore with an end button press fit therein. The hinge pin is shifted downward to the locked position by pressing down on the top portion of the actuating mechanism, and the hinge pin is shifted upward to the unlocked position by pressing the end button upward. A sleeve extends through the knuckles, and has an internal diameter that is approximately only 4/1000" larger than the external diameter of the hinge pin. These close tolerances result in reduced wear and tear on the hinge. To avoid inadvertent movement of the hinge pin, the hinge further includes a position retention mechanism.
