The anchor clamp has a transonic body (2) whose larger diameter rear end has an anchoring means fitted to it. The body (2) houses several conic sector segments (7). The actual number of sectors (7) being three. Each of them has on its face, opposite to the convex face designed to mate with the body (2), a semicircular longitudinal slot from the face of which project teeth (9). At the largest diameter end of each sector segment (7) in a projection (12) which forms a centering element for a helicoidal spring (13). This spring presses against the face (10) of each segment and against an end (14) of the anchor clamp body (2). Under pressure exerted by the aerial cable supporting cable (20). The sectors (7) are forced apart against the spring (20) is gripped by the teeth in the sector segments (7) which are forced together by a combination of spring (13) pressure and the transonic shape of the body (2). |
