Abstract
For the balancing of seismic streamer cables (1) circular ring or sleeve-shaped weighted bodies are adjustably attached at desired intervals on the cable. The weighted bodies can be resilient for temporarily enlarging an opening (3) to receive the cable therethrough and for closing onto the cable in use, or can be circular cross-sectional bodies formed by two parts (4, 5, 4', 5') partially connected together by a single pin (6, 6') and fastened together by a spring pin (7) or hook-shaped pivoted lever (8) engageable with a retainer pin (10).
