The invention relates to an anchoring dowel (11) for joining two bodies (7, 8). The dowel is composed of two contacting half-dowels (11a, 11b) whose opposing faces (13a, 13b ) are helical surfaces twisting in opposite directions. The projecting ends of the half-dowels are thus mutually spread apart with respect to contact zones (19a, 19b), which are compressed by the joined bodies (7, 8) so ensuring the anchoring of the dowel. |
