A security element comprises a fixed member comprising a clamping portion proximate a first end and a coupling portion proximate the second end and defining a slot extending along a slot axis. The slot comprises an interior surface comprising a plurality of recesses. An adjustable member comprises an engagement portion configured to house a portion of the coupling portion of the fixed member. A coupling element is configured to extend between a first coupling opening and a second coupling opening and is configured to couple the adjustable member to the fixed member through the slot, wherein the coupling element is configured to contact at least one of the plurality of recesses in the slot. A barrier is formed between adjacent recesses that is configured to prevent the coupling element from moving along the slot axis.

A securing apparatus for securing a valve lever in a set position comprises a base body; a sliding piece; and a screw element, wherein the base body and the sliding piece each have a clamping surface; wherein the sliding piece is displaceably supported at the base body along a longitudinal axis; and wherein the screw element is rotatably supported at the base body and has a thread that is in engagement with a mating thread of the sliding piece so that a position of the sliding piece relative to the base body along the longitudinal axis is restricted to a maximum spacing between the clamping surfaces that can be changed by a rotation of the screw element in order to clamp the valve lever between the clamping surfaces. Depending on a rotational position of the screw element, a blocking receiver formed at the screw element is aligned with a blocking receiver formed at the base body so that a blocking element, in particular a cable, can engage into both blocking receivers in order to block the screw element in this rotational position.

A gun lock for use in securing a weapon within a gun rack of a police vehicle or the like utilizes a housing supporting a pair of curved lock gates in curved travel paths between an abutting closed configuration and a separated open configuration. The curved lock gates are constrained in curved travel paths by a top plate and a lower plate and each define a curved gear rack. A coupling gear is rotatably supported within the housing and simultaneously engages both curved gear racks to provide movement of the lock gates between open and closed configuration. A solenoid operated latching mechanism secures the lock gates from movement away from the closed and locked configuration in the absence of an electrical activation. A key override is provided in the event of an electrical failure within the host vehicle.
