Abstract: The tongue material (2) is shaped, in a hot state, immediately after the extrusion thereof, preferably by means of a gear wheel acting upon the tongue material. The tongue material (4) is preferably longitudinally drawn after cooling below the solidification point thereof, with preferably a doubling in length. The final tongue profile (7) is thus achieved which displays a higher stiffness due to the stretching and may be adjusted to length or cut to length. The tongue (7), produced in the above manner, is finally mounted on the base body (8) of the drawn seal (1) by a spray application and forms the final drawn seal (1), together with the sealing body, also preferably mounted to the base body (8) by a spray application. The above is characterized not only by the good stability, but by the adjustable length of the tongue (7) and also a high security on manipulation. The final drawn seal (1) cannot be cut and resealed after installation, without leaving traces on the object to be sealed.

Abstract: A closed seal member has a channel extending through it and contains a holder with locking members for the irreversible holding of an end of a flexible band of metal, which end is introduced into the channel. The other end of the band is fastened in the seal member. The flexible band carries a detachable code carrier. Both the seal member and also the code carrier fastened on the band have a code which is identical for both or is a unique code. The code carrier is fastened in such an area of the band that the seal can be closed only after removal of the code carrier.
