The invention relates to a locking device, in particular for a motor vehicle, having a catch mechanism and a coupling device for connecting to a motor drive. The coupling device comprises a coupling lever, which by virtue of a plurality of engagement lugs is able to pivot a coupling lever. The engagement lugs can be detected in succession by the coupling lever and are arranged in this respect one behind the other. The invention further relates to a plastics component for the locking device. An engagement lug (14, 15) is formed by an element protruding from a main face of the coupling lever (12) in order to simplify production and to keep material costs and installation space to a minimum.
