The expanding plug (1) with an expanding part (2) has two diametrically opposite, axially open longitudinal slots (6a, 6b) which are offset through 90 DEG in the circumferential direction with respect to two diametrically opposite, axially closed longitudinal slots (5a, 5b). The axially closed longitudinal slots (5a, 5b) and the axially open longitudinal slots (6a, 6b) partially overlap axially, so that the expanding part (2) can be expanded in the overlapping region without the expanding element (3), which is used for expansion, moving. …<IMAGE>… |
