1. A cooler for at least one electrical energy storage element, the cooler comprising:
at least two manifolds,
at least one duct for heat-transfer liquid circulation, the at least one duct having ends which each penetrate into a corresponding one of said manifolds,
each of said manifolds comprising a collector having at least one opening for introduction and passage of said at least one duct, and a cover covering said collector in such a way as to define a volume, into which said at least one duct opens, for circulation of a heat-transfer liquid, and
each of said manifolds comprising at least one seal,
wherein said at least one duct and said cover are mechanically fastened together in a fluid-tight manner with said collector via interposition of said at least one seal:
between said collector and said at least one duct; and
also between said collector and said cover;
wherein said at least one seal, for at least one of said manifolds, comprises a seal which is compressed both:
between said collector and said at least one duct; and
also between said collector and said cover;
the collector including a groove;
the cover including a foot disposed in the groove of the collector; and
the collector further including teeth which crimp the foot of the cover between the teeth and the seal, to retain the cover in position on the seal.
