Claim:
A liquid dispensing assembly comprising: a supply hose adapted to supply a liquid; a dispensing member fluidly coupled to the supply hose and configured to dispense the liquid, the dispensing member including a first contoured engagement surface having circumferentially spaced convex portions and circumferentially spaced concave portions positioned intermediate adjacent convex portions; a support member having an elongate aperture therethrough configured to slidingly receive the supply hose and to releasably support the dispensing member at one end thereof, the support member including a second contoured engagement surface configured to mate with the first contoured engagement surface, the second contoured engagement surface having circumferentially spaced convex portions and circumferentially spaced concave portions positioned intermediate adjacent convex portions; and a magnetic coupling having a magnet and a magnetically attractive member, one of the magnet and the magnetically attractive member supported by the dispensing member and the other of the magnet and the magnetically attractive member supported by the support member, the magnetic coupling exhibiting a first magnetic force between the magnet and the magnetically attractive member when the first contoured engagement surface engages the second contoured engagement surface in a first position of the magnetic coupling and a second magnetic force which is less than the first magnetic force when the first contoured engagement surface is rotated to engage the second contoured engagement surface in a second position of the magnetic coupling, the first position defined when the concave portions of the first contoured engagement surface receives the convex portions of the second contoured engagement surface, and the second position defined when the convex portions of the first contoured engagement surface engage the convex portions of the second contoured engagement surface.
