ABSTRACT:
The rotatable cylindrical sleeve that comprises the female cable connector termination of a seismic streamer cable section is made in two telescoping parts. The two telescoping parts are indexed together by a shear pin to form a weak link assembly. If a streamer cable is snagged, the shear pin fails, allowing the telescoping parts of the sleeve to part company, releasing the snagged cable portions but without structural damage to the cable section. A feature of the device is its ease of retrofit.
