A sealing device for crushed-ice drink makers comprises an outer sealing element (3) having a sealing surface (10) which can be slidably engaged with a front wall (160) of an evaporator cylinder (120) of a crushed-ice drink maker (100), and an inner sealing element (2) which can be connected with the outer element (3) and at least partly inserted in a hole (170) in the front wall (160) of the evaporator cylinder (120). The inner element (2) has on the outside of it a plurality of sealing rings (6) able to engage with the hole (170) to create a second fluid-tight seal.
