FIELD: laying cables or similar components through walls. ^ SUBSTANCE: proposed transition device designed for passing at least one stretched line 41 through stuffed hole in wall 10 has clamping frame 11 and plurality of blocks 5 filling the latter. At least one of blocks 5 has through channel 51 to receive line 41, block 5 being suited to receive line 41 on one side of channel 51. Device also has separate tubular insert 1 made of flexible material. Insert 1 has in effect axial through slit 3 in its wall for its installation on one side of line 41 and its cross-sectional area corresponds in effect to that of channel 51 in block 5. Insert has plurality of radially separated layers 2 which can be set apart to adapt insert through channel 8 to line 41. ^ EFFECT: simplified cable laying procedure. ^ 12 cl, 8 dwg |
