An assembly locking device adapted to a normalized standard or fine thread of a thread shaft of a thread bolt, so that the locking device is positionable in a loss-proof manner on the thread of the thread shaft. The locking device includes: a cylindrical turn comprised of a plurality of helically wound turns, of a wire, a transition turn and adjacent to the second end of the helix is a blocking turn which has a negative pitch Pcompared to the holding turn, so that at least an end portion of the blocking turn is elastically displaceable in the axial direction of the central longitudinal axis between an insertion position and a blocking position. The end portion of the blocking turn forms the second end of the helix and in the blocking position is arranged radially outwardly of the transition turn and/or the holding turn.
