Abstract

A strain-relief device for cables, in particular optical waveguide cables, includes a lower part (10), which is in the form of a U in cross section, and an upper part (30). The lower part (10) is formed on its limbs (12) on one end side (16) with a pivot bearing and on the opposite end side (13) with latching tabs (14), which are arranged on the inner sides of the limbs (12). The upper part (30) includes at least two sprung lateral limbs (31), on whose outer side in each case at least one latching projection (35) is arranged, which latching projections (35), in the assembled state, latch behind the latching tabs (14) on the lower part (10). The upper part (30) also includes spindle means, which can be inserted into the pivot bearing in the lower part (10), and to a wire-guiding element (60), in particular for optical waveguide wires. The wire-guiding element (60) includes a lower part (40) and an upper part (50). The lower part (40) is formed in the longitudinal direction (L) with guides (46), which are formed between guide webs (45), clamping ribs (47) being arranged on the inner sides of the guide webs (45), and having first fixing means on the upper side (44). The upper part (50…
