A fastening element is provided, which is adapted to cooperate with a tie member to exert a compressive force on first and second components, the fastening element comprising an inner portion (50) resiliently joined to an outer portion (52), such that when a tensile reaction force is applied to the tie member as a result of the compressive force, the reaction force causes the outer portion (52) to be displaced relative to the inner portion (50). The fastening element may further comprise a washer (56) rotatably attached to the outer portion (52) by a cage (54). An indicator element for use with such a fastening element is also provided, together with a method of securing a first component to a second component by means of such a fastening element.
