ABSTRACT:
A method for opening an opening (10) using an elastic plug (2, 2′) whose outside diameter in a static state (rL), is larger than diameter (rp) of opening (10), and which plug has a cavity (12) at its end. An extending device (4, 4′) is inserted into plug cavity (12) so that the plug is tightly pressed around extending device (4, 4′). Plug (2, 2′) is extended by inserting extending element (20) of extending device (4, 4′) into plug cavity (12) so deeply that outside diameter (rV) of plug (2, 2′) is equal to, or smaller than, diameter (rp) of opening (10). The extended plug is inserted into opening (10), and its extension is reduced such that plug (2, 2′) closes opening (10) and adheres to it so tightly that extending device (4, 4′) is detachable from plug (2, 2′). A method for opening the opening (10) when closed by plug (2, 2′) is also disclosed.
