<p>The device has a clamp piece (10) with a cut (1000) extended from a surface (101) of the clamp piece in distance (D5). An elongated component (50) is located in the clamp piece, and has a part (51) to limit radial contraction of the clamp piece, to a preset value, in a zone extended between longitudinal limits (L1, L2). The limit (L1) is positioned at distance (D6) of the surface, where the distance (D6) has a value between distance (D5) and preset distance (D4) of an element (2). Another limit is positioned at third distance of the surface, where the third distance has preset value.</p> |
