• the novel key lock combines the advantages of a key lock, namely the quick and easy closing of the lock by plugging in the insertion, with the advantages of a padlock, namely the complete protection against loosening of male part and lock part against the direction of insertion under load, without the disadvantage the more expensive hooking, as in a padlock, to accept.
• the first latching mechanism has at least one, in particular two, latching lugs arranged on the latching tongue, which are each pivotable about a pivot axis, wherein the latching lug is acted upon in the direction of a locking position with an elastic biasing force and from this locking position by pivoting about the respective pivot axis is resiliently deflectable against the biasing force, wherein on the lock part to each locking lug a rigid latching hook is designed and arranged such that after insertion of the male part in the lock part in each case a latching nose with an associated latching hook cooperatively produces a latching connection.
• An automatic deflection of the locking lug against the elastic biasing force when inserting the male part in the lock part is achieved in that the locking lug each having an inclined surface which rises in the direction opposite to the plugging rising.
• two latching lugs are arranged on the plug-in part and two latching hooks on the latching part, wherein the two latching hooks are formed as respective U-shaped elevations on the plug-side end of the latching part.
• each has a leg of the U-shaped elevations a free end, wherein the legs of the U-shaped elevations are arranged with free end spaced apart such that a Distance between these legs of the U-shaped elevations is equal to or greater than a width of the latching tongue of the male part.
• the latching tongue has a parallel to the insertion direction elevation and the lock part has a groove parallel to the insertion direction, wherein the elevation and the groove are arranged and designed such that upon insertion of the Plug-in part in the lock part engages the survey in the groove and thereby performs the male part relative to the lock part.
• the second locking mechanism For automatically locking the second locking mechanism, the second locking mechanism is acted upon in the direction of the locking position with an elastic spring biasing force.
• the second locking mechanism is such arranged and formed so that it is manually movable against the elastic spring biasing force in the unlocked state.
