Closing device has a base member (5) with projections (3) which are pretensioned opposite the walls of the tubes and when the device is correctly positioned engage at the ends in the tubes. The closing device is fixed with the pretensioned projections and at least two adjoining projections have detent catches (13,14) which clamp with the walls. The projections can have a ring-shaped wall arranged on the base member whereby its side remote from the base member is closed by a head region (8) whose external contour corresponds to the internal cross section of the relevant tube.
