An electrical cell is secured in a trough shaped housing in a plate of a timepiece movement by a device located at the periphery of the housing. Said device comprises at least one member such as a washer with a cut-away edge held by means of a screw which moves it, from a rest position in which the cell is free, downwardly and inwardly into the housing to an operative position biting into the wall of the cell which is firmly held against a contact in the housing. |
