    Abstract: A device stops and retains a clamp on a wire. The device is mounted above a surface, which is preferably a deck of a vessel. The device comprises a fork that can engage with the clamp. The fork has a pair of teeth defining an opening therebetween, and the opening has a bottom. The fork has a first effective locking height defined between the bottom and the surface and height intended for retaining a wire lying within a first size range. The fork also has a second effective locking height defined above the surface and intended for retaining a wire lying within a second size range which is smaller than said first size range. The second locking height is greater than the first locking height, relative to the surface. The fork includes at least one guide member for mounting and securing an insert, preferably U-shaped, in the opening between the fork teeth, said insert having a bottom defining said second locking height. Optionally, the fork teeth have holes through which a locking bolt can be inserted.
