Abstract

Fremgangsmåte og apparat for for- bindelse av enden av et endeløst, slankt drivrør (50) med en nedsenket verktøys- streng. Apparatet har et første og andre forbindelsesstykke (10, 30) med gjennom- gående boring for å oppta det endeløse drivrør slik at dette i det minste delvis kan gå inn i det andre, nedre forbindelses- stykke (30). Kiler (20) som i det minste delvis omslutter røret har på innsiden fremspring i form av aksialsterke gjenger for å trenge inn i en tilstøtende flate på røret og danne en dreiefast forbindelse med dette. Kilene (20) er videre innrettet for samvirke med tappforbindelser i det nedre forbindelsesstykke (30) for dreief ast og torsjonsoverførende kopling til dette, og et kraftoverføringselement i form av en kilekloss (15) er anordnet mellom kilene og det første forbindelsesstykke (10) for å holde disse i trykkontakt med det ende- løse drivrør (50).
