The splaying body (21) has a frustoconical head with the smaller diameter oriented to the breaking groove (23), wherein the sleeve-shaped base body (10) has in the longitudinal direction (110) from an inside-bore directed surface (17) to an outside directed surface (16) a head receiving portion (115) followed by a tapering shoulder portion (14) and a central opening (12) having an inner cylindrical surface (13) configured to allow to pass the outer diameter of the pulling element (22). The sleeve-shaped base body (10) as well as the expander element (20) are made of aluminum or an aluminum alloy and a circumferential groove (18, 18') is provided in the inner guiding wall (19) around the outer directed section of the central bore (43) of the sleeve-shaped base body (10).
