Abstract: A portable electrical power supply device includes a battery, cables and a female connector to which is attached a cover aimed at attaching the connector to the battery. This cover notably attaches the female connector and the battery as such. This gives a compact, consistent and rigid assembly. No separate handling operations need to be planned to insert the female connector into the male connector and insert the battery into its housing. Besides, in at least certain embodiments, the rigid cover is shaped so that it does not take up a volume greater than that of the battery without a cover.
