<p>The invention relates to a strain relief device (1) arranged at an joining apparatus (2), having high tensile strength, for cables, said cables comprising an internal sheath (4) surrounded by a reinforcement sheath (5) consisting of reinforcement wires. The strain relief device comprises at one end, opposite to the joining apparatus, double conical surfaces (Kl, K2) having counter-directed conicity and least two clamping rings (10, 11) displaceable in the axial direction of the strain relief device, respective clamping ring having a hole with mirror-inverted conical surface complimentary to the conical surfaces of the strain relief device. The clamping rings are adapted to clamp the reinforcement wires between the double conical surfaces formed between the strain relief device and respective mirror- inverted conical surface of respective clamping ring. The hole in respective clamping ring (10, 11) has double conical surfaces (K3, K4, K3', K4' ) with counter directed conicity and the generix of which has different length. The invention relates also to a joining apparatus (2) provided with strain relief devices (1).</p> |
