The invention relates to a closing device (10) with a rotor (11) which has a cylindrical periphery (17) and which accommodates spring-loaded locking mechanisms on one side. With a closing device of this type, a pivoting tilting moment of the locking mechanisms may occur. A stator (21) for rotationally mounting the rotor (11) has a blocking channel (22) which is delimited by two flanks (23, 24) and into which the end of the spring-loaded locking mechanisms moves when the key is withdrawn, hereby preventing the rotor (11) from turning. Starting from a zero position, the rotor (11) can be moved into at least one other working position in two opposite directions (25, 26), respectively. The aim of the invention is to render the device more secure against break-in attempts by picking. To this end, there is a widened channel section (40) in the stator (21) on the flank (23) of the blocking channel (22) that is oriented in the direction of the tilting movement (25). Said widened channel section (40) has a larger inside width (41) than the rotor receiving element but is flatter than the radial depth (42) of the blocking channel (22). When the rotor (11) is moved into a rotation position in the direction of the tilting direction of the locking mechanism following manipulation, the locking mechanism rests on an inwardly pointing support surface provided inside the widened channel section (40) with its end. The locking mechanism therefore projects beyond the periphery of the rotor (11), hereby intercepting any rotation of the rotor (11) back (26) in the opposite direction of rotation from the other flank (24) of the blocking channel (22), resulting from further manipulation. |
