Device for storing trolleys, characterised in that it comprises a set of locks mounted in series inside a horizontal beam 1 from which there protrude the head 8 of the lock and its operating arm 9 subjected to a return spring, each trolley 2 having a prior deposit device 6, a chain 10 being fixed, on the one hand, to the control arm 9, and, on the other hand, to a key 11 for releasing the deposit of the prior deposit device 6, the length of this chain being such that in the rest position it is less than the minimum distance separating the operating arm 9 from the deposit device, so that it is necessary to rotate this operating arm in order to be able to use the key and that, after inserting a deposit element into the prior deposit device, the operating arm can return to the rest position under the action of the spring thus locking the lock associated with the previous trolley. <IMAGE>
