A light concrete nail consists of a dowel (1) which has two lateral openings (3, 4) and inwardly directed tongues (5, 6) whose inner edge parts (7, 8) are juxtaposed and form an inner wedge. A locking pin, provided for driving in the dowel, has two limbs (11, 12) with ends inclined towards one another in order to form a gap. When the locking pin (10) is driven into the dowel (1), the wedge formed by the tongues (5, 6) penetrates into the gap formed by the limb ends, and the latter are guided into the light concrete. <IMAGE>
