The electric strike comprises a keeper (15) having a projecting portion (19) which pivots about a first pivot axis (18) and which is arranged to co-operate with a latch bolt, a spring (20) for urging the keeper to its door-locking position, a lock lever (23) which pivots about a second pivot axis (25) and which comprises a hook-shaped retention element (27) for locking the keeper (15) in its door-locking position, and an actuator for actuating the lock lever (23) which comprises a compression spring (31) urging the lock lever (23) to its locking position and an electromagnet (42) exerting, when energized, a counter force onto the lock lever (23) to move it to its unlocking position. To enable a compact and reliable construction notwithstanding the fail-secure arrangement of the electric strike, the first and second pivot axes (18, 25) are substantially parallel, the electromagnet (42) has a fixed core (44) which is arranged to directly attract the lock lever (23) and the outermost edge (21) of the keeper (15) is situated on the other side of a plane ² which comprises the second pivot axis (25) and which passes through the engagement element (28) for the lock lever (23) on the keeper (15) than the first pivot axis (18)
