An electronic pen has a body which comprises a casting (2a, 2b) which are joined to be separable, and electronic equipment arranged inside the casting. A girdle (3) is arranged with a close fit round the joined casing parts (2a, 2b) . The casing (2) and the girdle (3) have coacting locking means which limit the movement of the girdle in the longitudinal direction of the pen (1) in such manner that at least the girdle (3) is destroyed as the locking is broken. |
