Device for sealing an actuator includes a drive shaft (2) and an elongated body (3) which move, relatively to each other, along their longitudinal axis, covered by a sleeve (4) which covers at least partially both the elongated body and the drive shaft, the sleeve having a first portion conformed with the bellows (41) and a second portion (42) having the shape like the elongated body so that it may be fitted on it and blocked at its end, the bellows portion being positioned in correspondence of the shaft (2) and locked on it at its end so that the sleeve is integral with the shaft itself.
