ABSTRACT:
A tension relieving device for seismic cables or cable sections having a stretch element (4) which is passed in loops between two end pieces (1,2) designed to be attached to end contact pieces on the seismic cable. The stretch element (4) is passed in at least two loops, with at least four lengths (8) in the longitudinal direction of the device, in that the loops are passed through holes (6) and curved, tubular guides (12) in the end pieces. On their lengths (8) the stretch elements (4) are equipped with stoppers (10) with diameters greater than the holes (6) in the end pieces (1,2). In the central area of the end pieces (1,2) between the stretch element guides a preferably central opening (9) is made to allow the cable's wires etc. to pass through.
