Roller skate, the chassis (1) of which is equipped with a latch (35) equipped with nibs (36,37) which automatically lock the bars (26,27) of a boot in notches (33,34) of the chassis under the tension of a spring (44). The latch can be held in the open position by a catch (47) which can be actuated by one of the bars (26). The chassis is also equipped with a retractable abutment (30) which opposes the movement of the latch in the absence of any boot, this abutment being parted from the latch by one of the bars (27) of the boot when the boot is being put on. This retractable abutment on the one hand ensures that the two bars of the boot are suitably engaged in the notches in the chassis and, on the other hand, prevents inadvertent and dangerous closure of the latch when manipulating the skate.
