The device consists of a single-block body (2) with a cover inside it, a gear wheel (5) resting on an inclined bed and a spring (6) in contact with the gear wheel to force it into contact with the cord, wire (20) or cable. The gear wheel has hollows or apertures for reducing the overall weight and the cable, cord element or wire runs through the interior of the resulting channel (4) in the longitudinal direction. |
