<p>A seal body formed of a pot-shaped element or housing and a cover contains a compartment within which there is inserted a holder. The holder comprises a substantially U-shaped metallic element having leg members from which protrude resilient tongues directed away from the holder ends towards the center region of the holder. The tongues extend at an inclination towards the oppositely situated holder leg or leg member. For each leg member there are provided two tongues and, in each case, one of the tongues of one of the leg members intersects, in the hollow space between the leg members, with one of the tongues of the other leg member and forms a locking or blocking element. Coacting with such locking element are catch elements provided at both ends of a metallic strip. These catch elements are formed by openings. If one end of the strip is introduced into a receiving opening of the seal body and which opening is accommodated to the dimension of the strip end, and into the space between the leg members of the holder, then the opening is caught at the tongues of the one locking element and no longer can be retracted. To close the seal the other end of the metallic strip is guided into the seal body between the tongues of the other locking element until it is irreversibly caught by means of its strip opening in the same manner.</p> |
