A filter cartridge is for a vehicle fluid filter group that includes a filter body and cartridge engagement members in the filter cartridge and body engagement members in the filter body. The cartridge engagement members and body engagement members are configurable by mutual axial movement between an engagement configuration and a disengagement configuration. The cartridge filter includes an end plate with the cartridge engagement members arranged around the cartridge axis. The cartridge engagement members include two blocking groups, each blocking group including a blocking element. Each blocking element includes a stem and a tooth laterally projecting from the stem and defining an engagement undercut. In the blocking configuration, the tooth is in a housing region of the body engagement members, and an engagement projection is housed in the undercut. In axial movements, each stem yields elastically radially and/or laterally upon action of the engagement projection on the tooth.
