Embedded in a slab of concrete (1), Fig. 3, are lugs (15) which are shaped in the form of a hairpin which is symmetrical relative to the plane defining a reinforcement (9) to be fixed to the lug. The head (13), Fig. 2, of the hairpin shape which is embedded in the material of the slab has a section in the form of a polygonal or curvilinear loop having two convergent sides (16) which are bent in the vicinity of their point of convergence in such manner as to form two parallel tabs (17). The latter have a portion (17a) which projects from the rear face (2) of the slab. The projecting portion (17a) defining therebetween a gap in which the reinforcement (9) can be inserted and fixed. <IMAGE> |
