摘要： An expansion plug has at least one tensioning member, an expansion means formed by a system of at least two expansion tubes encircling the tensioning member and fitted one within another, each of the expansion tubes being provided with a series of slots which are equally spaced in a circumferential direction to retain peripheral sections of the expansion tubes between the slots, the slots extending over a part of a length of the expansion tubes, the tensioning member and the at least two expansion tubes being dimensioned and shaped so that by inserting an axial relative movement the peripheral sections are radially expanded in order to achieve an anchoring effect, the slots of the at least two expansion tubes having a shape which is helical in relation to an axis of a respective one of the expansion tubes, the slots having a slope such that the slope of radially adjacent ones of the expansion tubes are of mutually opposite hand, the expansion tubes being arranged to be non-rotatable relative to one another.
