Claims (6)

1. Verriegelungseinsatz zum Aufnehmen einer Befestigungsvorrichtung, gekennzeichnet durch:
eine Metallhülse (10) mit einem Innengewinde (11), daß sich in Längs­ richtung durch die Metallhülse (10) erstreckt und die Befestigungsvorrichtung aufnimmt, zwei metallischen Flanschen (13), die jeweils an zwei gegenüber­ liegenden Enden der Metallhülse (10) angeordnet sind und am Umfang gerän­ delt sind, um mehrere nach außen stehende Vorsprünge (131) zu bilden, zwei Öffnungen (101), die jeweils an zwei gegenüberliegenden Seiten der Metall­ flansche (13) angeordnet sind, und einem Wandabschnitt (1051-1053), der in Richtung zum Innengewinde (11) verformt wird bis zu einem solchen Aus­ maß, daß die Metallhülse (10) einen Reibungseingriff mit der Befestigungs­ vorrichtung entwickelt; und
einen Kunststoffmantel (20) in Ringform, der eng um die Metallhülse (10) aufgesetzt ist, um einen Raum zwischen der Metallhülse (10) und dem Kunststoffmantel (20) für die elastische Ausdehnung des verformten Wandab­ schnitts (1051-1053) in Reaktion auf die fortschreitende Aufnahme der Befe­ stigungsvorrichtung im Innengewinde (11) der Metallhülse (10) zu schaffen.1. Locking insert for receiving a fastening device, characterized by :
a metal sleeve ( 10 ) with an internal thread ( 11 ) that extends in the longitudinal direction through the metal sleeve ( 10 ) and receives the fastening device, two metallic flanges ( 13 ), which are each arranged at two opposite ends of the metal sleeve ( 10 ) and are knurled on the circumference to form a plurality of outwardly projecting projections ( 131 ), two openings ( 101 ), which are each arranged on two opposite sides of the metal flanges ( 13 ), and a wall section ( 1051-1053 ) which is deformed in the direction of the internal thread ( 11 ) to such a measure that the metal sleeve ( 10 ) develops a frictional engagement with the fastening device; and
a plastic jacket ( 20 ) in a ring shape, which is placed tightly around the metal sleeve ( 10 ), a space between the metal sleeve ( 10 ) and the plastic jacket ( 20 ) for the elastic expansion of the deformed Wandab section ( 1051-1053 ) in response the progressive inclusion of the BEFE stigungsvorrichtung in the internal thread ( 11 ) of the metal sleeve ( 10 ) to create. 2. Verriegelungseinsatz nach Anspruch 1, dadurch gekennzeichnet, daß der Kunststoffmantel (20) aus einem mittels Wärme schrumpfbaren nichtmetallischem Kunststoffmaterial besteht.2. Locking insert according to claim 1, characterized in that the plastic jacket ( 20 ) consists of a heat-shrinkable non-metallic plastic material. 3. Verriegelungseinsatz nach Anspruch 2, dadurch gekennzeichnet, daß der Kunststoffmantel (20) entweder aus Polyphenyl-Fluorid, Polyoliphin, Neopren oder Teflon gefertigt ist.3. Locking insert according to claim 2, characterized in that the plastic jacket ( 20 ) is made either of polyphenyl fluoride, polyoliphin, neoprene or Teflon. 4. Verriegelungseinsatz nach Anspruch 1, dadurch gekennzeichnet, daß die Öffnungen (101) eine reduzierte Dicke besitzen, so daß sie radial nach außen verformt werden können in Reaktion auf ein auf eine einseitige Belastung mit einer Kraft, die ausreicht, um die Metallhülse (10) bis zu einem Ausmaß zusammenzudrücken, das eine leichte Aufnahme der Befestigungs­ vorrichtung in der Metallhülse (10) verhindert.4. Locking insert according to claim 1, characterized in that the openings ( 101 ) have a reduced thickness so that they can be deformed radially outwards in response to a one-sided load with a force sufficient to the metal sleeve ( 10th ) to compress to an extent that prevents easy mounting of the fastening device in the metal sleeve ( 10 ). 5. Verriegelungseinsatz nach Anspruch 1, gekennzeichnet durch eine Montagestruktur (30), die ein um den Verriegelungseinsatz gegosse­ nes Kunststoffmaterial umfaßt.5. Locking insert according to claim 1, characterized by a mounting structure ( 30 ) comprising a cast around the locking insert NES plastic material. 6. Verriegelungseinsatz nach Anspruch 5, dadurch gekennzeichnet, daß die Montagestruktur (30) aus Melamin, Bakelit, Nylon oder einem Epo­ xid-Harz gefertigt ist.6.
