<p>Intersecting slots and peripherally located claws run out from a central hole passing through a clamping clawed plate for air-layer anchors. Each segment (7), bounded by adjacent slots (6), bears a lug (8) protruding from the surface of the clawed plate (1) in the direction opposite to that of the claws (4). This has a clamping surface (9) facing the central passage (5). The plate is made of flexible material. Lug width is pref. only a fraction, up to a third, of the length of a slot. Each lug may have radially aligned reinforcing ribs (10) formed on it. The plate can have an elliptical periphery, with radial slots inclined to its longitudinal axis.</p> |
