A height adjustment assembly for a drop hose on an irrigation machine is composed of an elongated bracket having a first end provided with a pair of fittings, and a second opposite end provided with a drop hose retention ring; the drop hose retention ring formed with an opening adapted to permit a drop hose to slide through the opening, the opening defined by an interior surface provided with a pair of diametrically opposed open slots, and a pair of diametrically opposed locking recesses. A key lock fitting is adapted for connecting aligned hose ends of the drop hose and is provided with a pair of diametrically-opposed keys which, in use, are adapted to slide through the pair of opposed open slots and, upon ninety degree rotation of the diametrically-opposed keys, to be received in the pair of diametrically opposed locking recesses.
