A sinker bar (2) for use with a hydrocarbon well apparatus connected to an operating cable (not shown) through a cable head (3) comprises a top endpiece (4), a body (5), a bottom endpiece (6) and a longitudinal slot (26). The slot permits lateral engagement of said bar onto said cable and includes first connection means at its lower end (in use) for connection to said cable head. The bar may also include at its other end second connection means for connection to a fishing head (1). The connection means takes the form of a twist-lock arrangement. The apparatus is connected to the cable head by means of a threaded bore. If required, several sinker bars (3) can be connected in series, around the cable and above the cable head. |
