A filter group (10), comprising: a support body (25) provided with at least an engaging seating (252) and a filter cartridge (30) provided with a substantially toroidal filter wall (33) and a support plate (31) provided with at least an engaging tooth (311) able to snap-engage to the engaging seating (252), where the engaging seating (252) is provided with a rest surface (253) lying on a substantially perpendicular plane to the axis (A) of the filter wall (33) and two opposite flanks (256, 257) that rise from opposite sides of the rest surface (253). The particularity of the invention is that at least a flank (257) of the flanks (256, 257) comprises a first portion (2571) substantially squared with respect to the rest surface (253) and a second portion (2572) axially prolonging the first portion (2571) and defining a disengaging ramp that is inclined with respect to the lie plane of the first portion (2571). |
