The device has a box body (1) on which a spike (11) is positioned, where the body is arranged on a support (10). The support authorizes vertical displacement of the spike. A projecting part is placed on the support. A groove (20) is formed on a battery compartment (2). A hole (21) guides and receives the spike. An upper face of the spike forms an angle higher than angle of the groove. The angle unlocks the compartment from the body by any object of diameter lower than diameter of the hole and to translate the compartment from the body. |
