1. A cooling element system for use within a cooling device of a closed-circuit respirator, the cooling element system comprising:
a plurality of cooling elements, each of the plurality of cooling elements comprising an element housing, which has a liquid-tight closure and is filled with a coolant or fillable with a coolant, wherein the element housings are connected to provide a common mounting arrangement of the plurality of cooling elements within the cooling device; and
a collar enclosing the plurality of cooling elements in the common mounting arrangement, the collar having a carrying area configured to allow for carrying of the plurality of cooling elements in the common mounting arrangement via the carrying area, whereby one or more of the plurality of cooling elements in the common mounting arrangement is removable from the cooling device via the carrying area and one or more of the plurality of cooling elements in the common mounting arrangement is insertable into the cooling device via the carrying area, the collar being configured to press one of the plurality of cooling elements in a direction of another one of the plurality of cooling elements and to press the another one of the plurality of cooling elements in a direction of the one of the plurality of cooling elements.
