Abstract

A housing is disclosed which may be used for a tachograph. The housing includes a battery holder and at least one fastening element arranged to fasten the battery holder to the housing. With the housing it is possible to mount a battery in an exchangeable manner while preventing the possibility of manipulating the components inside the housing during a changing of the battery. When the battery holder is mounted on the housing, the fastening element can only be accessed from the inside of the housing.
