A device that can be applied to cartridges for water equipment, intended to receive a rotary operating member ( 9 ) for the purpose of promoting the structural unification of the largest possible number of parts making up the cartridges, where the rotary fitting ( 17 ) inside the cartridge is by itself not provided with a control pin and instead has a coupling means ( 16 ) and where the control pin of the cartridge is made separately from the internal rotary fitting and has an internal coupling means complementary to the coupling means presented by the internal rotary fitting and external coupling means ( 10 ) suitable for meeting the requirements of a handling member for which the cartridge is arranged. The internal rotary fitting of each type of cartridge can thus be unified, just as other parts of the cartridge, and can be provided with a unified coupling means, and with the cartridge, one can coordinate several control pins ( 18 ), all provided with one and the same unified internal coupling means complementary to the unified coupling means presented by the internal rotary fitting and presenting diverse external coupling means suitable to meet the requirements of different operating members.
