Multiple engagement locking device

A locking device comprising:

• a locking mechanism,
• a motor drive,
• an actuating lever comprising a pair of engagement lugs arranged in succession, wherein the actuating lever is operatively coupled to a handle,
• an unlocking lever operatively connected to the locking mechanism, wherein the unlocking lever defines a slotted hole,
• a coupling lever which includes a pin positioned in the slotted hole of the unlocking lever so that movement of the coupling lever moves the unlocking lever, wherein the coupling lever is, in an “unlocked state”, operatively coupled to the actuating lever by the pair of engagement lugs such that movement of the actuating lever moves the coupling lever and is, in an “locked state”, operatively decoupled from the actuating lever and wherein the coupling lever is operatively coupled to the motor drive such that actuation of the motor drive moves the coupling lever, for shifting between the “unlocked state” and the “locked state”,
• wherein at least one of the engagement lugs includes a plastic component connected to the actuating lever in a manner selected from the group consisting of:
• overmoulding, latching using one or several latching elements, one or several interlocking elements, and one or several pins engagement;
• wherein at least one of the engagement lugs is made of metal with the plastic component surrounding and/or enclosing at least one of the metal engagement lugs;
• and
• wherein the coupling lever is partly circular and contains a lateral protruding projection that can engage the engagement lugs of the actuating lever.
