Abstract: The invention relates to the attachment of a mobile phone battery in which the battery (9) is pushed in the horizontal direction, for example in the direction of the surface of the phone, into a recess (2) formed in the casing (1) of the phone. The sides of the battery (9) are equipped with tabs (10, 10'), which slide under the tabs (5, 5') of the tabs on the sides of the recess (2) in such a way that these hold the battery in place in the vertical direction. Holding of the battery (9) in place in the horizontal direction is arranged with at least one locking element (12), which according to the invention is located on the side of the battery and locks, when viewed in the direction of pushing, behind the tab (5') on the side of the recess in such a way that the tab (5') functions as an element that holds the battery in place simultaneously in both the horizontal and vertical direction.
