Abstract

Eine erfindungsgemäße Steckverbindung zur Verbindung von zwei Gestängeschüssen eines Bohrgestänges weist einen Verbindungsstecker (5) an einem Ende eines ersten der Gestängeschüsse und eine Verbindungsbuchse (9) an einem Ende des zweiten Gestängeschusses auf und ist dadurch gekennzeichnet, dass der Verbindungsstecker und die Verbindungsbuchse spiralförmig verlaufende, ineinandergreifende Führungsvorsprünge (6,8) und/oder Führungsnuten (7) aufweisen. Ein erfindungsgemäßer Gestängeschuss für ein Bohrgestänge weist an einem seiner Enden einen entsprechenden Verbindungsstecker und an dem anderen Ende eine entsprechende Verbindungsbuchse auf.
