The assembly has a basin (10) with a hollow hemispherical inner surface, a recess and two pins. Another basin (20) includes a hollow hemispherical inner surface and bores for discharging air/sand mixture, where a hole is formed to receive the air/sand mixture. The latter basin includes two notches corresponding to the pins of the former basin, where the pins are engaged with the notches to form a body (30). A seal (36) is fitted into the hole that receives the air/sand mixture. The former basin includes lugs for gripping during unscrewing of the former basin from the latter basin.
