<p>The clamp (10) has anchorage branches (12, 14) over mounted with a curved coupling part (16), where the clamp is made of plastic. Each branch has a rod forming portion (20) extended by a perforation end (22). Flexible non-return fins (24, 26) extend freely opposite to the rod forming portion. Flexible links (28, 30) are connected to the respective non-return fins and the rod forming portion for retaining the fins, when the fins are spaced from the rod forming portion such that the branches are blocked in translation, when the branches are driven in a direction opposite to their deflection.</p> |
