Abstract: To disassemble an arrangement comprising a first part (1) with a first opening, a second part (2) with a second opening and a cavity, and a connector (3) with a first portion (31) and a second portion (32) inserted through the first opening and the second opening into the cavity for connecting the first and second parts (1, 2), a pressure difference is used for forcing the second portion (32) out of the cavity. Said pressure difference may involve firstly changing a surrounding pressure, such as slowly increasing the surrounding pressure, and secondly changing the surrounding pressure, such as quickly decreasing the surrounding pressure. The arrangement is arranged to not respond to said firstly changing and to respond to said secondly changing for said forcing out. The connector may comprise a third portion (33) with upper parts of legs, the first portion (31) comprising a head portion, and the second portion (32) comprising lower parts of the legs.
