ABSTRACT:
A fastening element comprises a tie bolt (1) and a clamping wedge (2) which for the purpose of transporting and insertion into a bore hole (24) are clamped together via a flange (5), which at the same time is used for attachment of a load (25) to a ceiling (23). To prevenr trouble when inserting the clamping wedge (2), it is provided on its outer face (11) with protrusions (21) which, in the non-extended state of the fastening element, abut on an open passage (19) of the flange (5), while otherwise the outer face (11) of the clamping wedge (2) has free play in respect to the open passage (19) of the flange (5).
