Filter cartridge with command device

A filter group of a fluid, wherein said filter group extends along a main axis and comprises:

• a filter cartridge;
• a base assembly engaging said filter cartridge along the main axis;
• said first engagement members comprised in the filter cartridge and second engagement members comprised in the base assembly, respectively shaped to engage each other in a blocking configuration in which the filter cartridge and the base assembly are mutually axially blocked;
• wherein the filter cartridge extends along a cartridge axis and comprises at an axial end an engagement plane on which said first engagement members are made, comprising at least two tooth elements diametrically opposite the cartridge axis;
• wherein each tooth element extends in height from the engagement plane parallel to the cartridge axis, comprising a stalk and a head, so that in the blocking configuration said head is engaged by the second engagement members;
• wherein each tooth element is elastically yielding in a radial direction, so that said blocking configuration is achievable following radial movement of the tooth element;
• wherein the first engagement members comprise for each tooth element a command device which extends radially from the tooth element, wherein actuation of the command device involves the radial movement of the tooth element:
• wherein the command device is positioned at an intermediate distance between the engagement plane and the head of the tooth element;
• a blocking housing in which, in the blocking configuration, the tooth element is housed, the blocking being of a shape complementary to the tooth element.
