The invention relates to a sleeve (1) for interconnecting rods (3, 5) provided with threads. The sleeve (1) has an opening in each end, said openings preferably having a different size and/or form. The inside form of the sleeve (1) is such that when the rods (3, 5) are combined to a mutual threaded engagement the sleeve (1) can be axially fitted to the overlapping area of the combined rods (3, 5). The inside dimension of the sleeve (1) is such that it makes separation of the rods (3, 5) in their position fitted on the overlapping area impossible as well as elimination of the mutual thread engagement. The sleeve (1) enables a rapid, simple and reliable joining of rods (3, 5) provided with threads with a free choice of the length of the overlapping area. |
