FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to safety couplings. Safety coupling includes crown (1), roller (2), tray (3), retainer (4), holder (5), housing (6), pin (7), spring (8), locking outer ring (9, 10 ) and washer (11). Roller (2) is able to disengage from housing (6), pin (7) is able to act on retainer (4) during rotation of housing (6), retainer (4) is able to act on roller (2), moving it to axis of rotation, with subsequent fixation. At that, crown (1) and housing (6) freely rotate relative to each other.
EFFECT: ease of use.
