A method for reconnection and connection of sensor groups, especially hydrophone groups or channels in a seismic cable, where the active sections in the seismic cable are connected with electronic modules or one another via connector plugs, is based on the principle that a specific number of hydrophone groups are connected symmetrically on each side of each electronic module. The number of connected hydrophone groups on each side is identical and constitutes at least one respective active section. A summation of a set of hydrophone groups in a section is performed automatically by connecting this section with another section or by connecting a respective section and the electronic module.

A reinforcing device to achieve stable fastening points for the inner portion (2) of seismic cables, especially cables that are towed laterally displaced in parallel in relation to the towing vessel and provided with at least two layers of armoring (5,6) intended for absorbing stretch loads on said cable, comprises a fastening means on at least one of the end areas of the inner portion (2), and gripping surfaces for external equipment and shaped with at least two securing chambers (3,4). For assembling the outermost layers of armoring (5,6) of said cable are separated and inserted into one chamber each (3, 4), wherein they are secured to form an integrated connection with said casing (2).
