The seal inlays of the keys of the wind instrument, which are applied against the rim (5) of the holes (3) determining the pitch, are fitted to the rim of the holes to be closed by means of a nonrigid elastic plastic which is solidified in situ. During the molding, the keys are braced in the position corresponding to their closed position in the finished instrument by a brace which is removed after the molding or by a flexible covering which remains after the molding on the nonrigid elastic solidified plastic.
