ABSTRACT OF THE DISCLOSURE A thrust plate which bears on a rock face is connected to a load-bearing termination on one end portion of an elongate member, e.g. a hollow rope, extending along a hole bored into the rock. An anchorage medium (not shown) fills the hole, anchoring the elongate member in the rock, and extends between the end portion and the surrounding portion of the termination, securing these two portions together.

Une plaque de poussée (11) s'appuyant sur une surface de roche (3) est reliée à une terminaison porteuse (6) sur une partie terminale (4a) d'un élément de forme allongée (4), par exemple un câble creux, s'étendant le long d'un trou (1) foré dans la roche. Un milieu d'ancrage (non illustré) remplit le trou (1), ancrant l'élément de forme allongée (4) dans la roche, et s'étend entre la partie terminale (4a) et la partie périphérique (7) de la terminaison (6), assujettissant ces deux parties ensemble.
