Abstract
Coverings for structures which can be installed in the ground are known. In order to lock the covering on the structure, closures are known which comprise a snap bolt which is designed in such a way and is mounted movably on the covering (20) against the force of a spring device in such a way that, during closing of the covering (20), the snap bolt is forced back and snaps in behind a counterbearing (14, 14′) fixed to the structure in a closure position. To simplify the arrangement and also to improve durability, it is proposed that the snap bolt is mounted in a housing (40) which can be fastened in a housing receptacle of the covering (20).
