Abstract
A device is described for a system for conducting tests of a well, pipe or the like, where a plug of a removable material is inserted in a pipe through a well to carry out said tests. The device is characterized in that the wall parts of the pipe comprise channel borings (3,4,8) that set up fluid connections between the well space (70) and the well space (72) above and below, respectively, the plug, and that it comprises a closing body that can close the fluid connection permanently. The channel boring is preferably defined by an axial hollow space/chamber (4) in which a piston is arranged, said piston can be readjusted by an axial movement from a first position where there is fluid connection through the channel and a second position where the connection is permanently closed and can not be reopened.
