The invention relates to a device for assembling stacked annular filtering elements under constant pressure. The device comprises a support which provides an abutment for one end of the stack of filtering elements, a presser member which provides an abutment for the other end of the stack, and a calibrated spring which biases the presser member towards the support while trapping the stack of elements between the two abutments. The device is useful for the manufacture of filters used particularly for the filtration of oils.
