Abstract: The invention concerns a catching device (1) between a first structure (2) and a second structure (3), characterized in that it comprises at least one bolt (5) linked to the first structure and mounted in opposition to at least one elastic return (9) tending to bring it back to a retracted position, a stop (10) corresponding to the second structure being adapted to maintain it in a taut state when the latter is proximate the first structure, such that when the first structure is rapidly spaced apart from the second structure, each bolt is engaged with at least one corresponding retainer (4) so as to limit the relative spacing and, when the first structure is slowly spaced apart from the second structure, each bolt and corresponding retainer remain separated, thereby allowing complete opening between the first structure and the second structure.
