Abstract

Pluggen ifølge oppfinnelsen omfatter et legeme (16) med en lengdeakse (X-X') og en radielt ekspanderbar, ringformet enhet (18). Den ringformede enheten (18) har en periferioverflate (39) for å presse mot en kanal og en periferioverflate (57) for å presse mot legemet (16). Den ringformede enheten (18) omfatter, rundt lengdeaksen (X-X'), flere blokker for radiell ekspansjon (40, 42). Hver blokk (40, 42) har en første lagerflate (44), en andre lagerflate (46) og to sideflater (48A, 48B) som vender mot en respektiv sideflate (48B, 48A) av minst én vedsidenliggende blokk (42, 40). Blokkene (40, 42) kan bevege seg i forhold til hverandre mellom en radielt inntrukket stilling og en radielt ekspandert, innkoblet stilling der hver sideflate (48A, 48B) til én blokk (40, 42) står i kontakt med en sideflate (48B, 48A) av den vedsidenliggende blokken (42, 40).
