A fastener comprises a shank (10) for extending through an opening (60) from a near side (56) to a far side (58) of a wall and a catch (20) retained in the shank of the fastener, in which the catch has first and second orientations in which, respectively, it projects less and more beyond the profile of the shank, whereby the catch can pass through the open-ing in the first orientation but the catch enggages the far side of the wall and prevents withdrawal of the shank from the opening in the second orientation, the catch being supported by a shoulder (42) when the shank is tensioned by a nut (50). Swivelling of the catch is controlled by rotation of the shank.
L'invention concerne une attache qui comporte une tige (10) conçue pour traverser une ouverture (60) d'un bord proximal (56) à un bord distal (58) d'une paroi, et un crochet (20) fixé dans la tige de l'attache. Ce crochet a une première et une seconde position dans lesquelles il dépasse plus ou moins le profil de la tige, ce qui permet audit crochet de traverser l'ouverture lorsqu'il est dans la première position, mais de s'accrocher à la partie distale de la paroi lorsqu'il est dans la seconde position, ce qui empêche ainsi la tige de se retirer de l'ouverture, le crochet étant supporté par un épaulement (42) lorsqu'un boulon (50) serre la tige. Le pivotement du crochet est commandé par la rotation de la tige.
