Abstract
A connection system for connecting external devices to specified locations on a marine seismic streamer. Inner collars having raised bosses are clamped to the cable at specified locations along its length. Each inner collar forms a circular race encircling the cable. An external device is attached to a pair of cuffs in the form of C-shaped cylindrical rings each with a circular inner surface. A gap in the ring interrupts the inner surface. The width of the gap is greater than the diameter of the bosses so that the cuffs may be slid onto the collars when the gaps are aligned with the bosses. The bosses are circumferentially offset when the cable is in its normal operating state to lock the cuff and the external device to the collars. The cuffs and the external device can be installed on or removed from the cable by twisting the cable to align the bosses and sliding the cuffs onto or off of the collars. When installed, the cuffs ride on the races to allow the cable to rotate inside the cuffs.
