1. A locking fixture, comprising:
a housing including a bore and a male thread, the housing installable within an opening;
an actuator shaft having first and second opposite ends, the actuator shaft rotatably received within the bore of the housing through a limited rotation extent, the second end of the actuator shaft exposed outwardly of the housing;
a seal received between the first end of the actuator shaft and the housing;
a locking tongue supported on the second end of the actuator shaft and including an actuating section extending from the actuator shaft;
first and second gaskets received on opposite sides of the locking tongue, the first gasket sealing the locking tongue with respect to the housing and the second gasket sealing the locking tongue with respect to the second end of the actuator shaft;
a screw sleeve including a female thread received on the male thread of the housing, the screw sleeve cooperating with the housing to secure the locking fixture with respect to the opening;
a blind hole extending longitudinally defined in a region of an end surface housing section of the housing into which a cylindrical pin is pushed;
a rotation limiter located in the bore and sealed between the seal and first gasket, the rotation limiter operable to limit the rotation extent of the actuator shaft; and the actuator shaft sealed at each of its opposite ends with respect to the housing bore by the seal and the first and second gaskets;
wherein the rotation limiter comprises the cylindrical pin located within an interior of the housing, and engageable with at least two stop surfaces on the actuator shaft;
wherein the at least two stop surfaces are disposed at respective ends of a recess in the actuator shaft; and
wherein the actuator shaft comprises a first cylindrical section having a first cylindrical section diameter and a second cylindrical section having a second cylindrical section diameter,
the first cylindrical section having a greater diameter different from the smaller second cylindrical section diameter, wherein the recess with a reduced diameter is located in an end region of the first cylindrical section,
wherein the cylindrical pin extends into a transition region between the first and second cylindrical sections at a front exposed end, whereby the cylindrical pin is brought into contact with the recess in the actuator shaft.
