Abstract: In order to lock a housing that consists of at least two parts, particularly a plug connector housing, a locking system that functions similar to a toggle lever mechanism is provided. In this case, a locking plate is arranged within a shell-shaped sliding element to both sides of a first and a second housing half and movably held on bearing pins on the second housing half, wherein latches are provided on the first housing half and engage into window openings provided in the locking plate for this purpose when the sliding element is displaced into its locking position in order to hold together the two housing halves.

Abstract: In order to lock a housing that consists of at least two parts, particularly a plug connector housing, the invention proposes a locking system that functions similar to a toggle lever mechanism. In this case, a locking plate (10) is arranged within a shell-shaped sliding element (20) to both sides of a first and a second housing half (3, 6) and movably held on bearing pins (7) on the second housing half (6), wherein latches (4) are provided on the first housing half (3) and engage into window openings (12) provided in the locking plate (10) for this purpose when the sliding element (20) is displaced into its locking position in order to hold together the two housing halves (3, 6).
