The mechanical seal for sealing off a shaft relative to a housing (2) contains a sliding pair, the elements of which are an annular gland packing (7), which is accommodated in a seat (10) of a sprung, axially movable holder (9), and an inflexible ring (8). The inflexible ring (8), which is hermetically connected to the housing (2), enters the seat (10) of the holder (9) along the axis (4) of the shaft (1) until it comes up against the gland packing (7). The gland packing (7) is hermetically connected to the shaft (1) by arranging the holder (9) on the shaft (1). <IMAGE>
