Abstract: In a brace part for the driving rod brace (4) of a window, the housing (10) is attached to a jacket rail (9) via brackets (16, 17). The jacket rail (9) has recesses (18, 19) through which the brackets (16, 17) are guided. The brackets (16, 17) with bends (22, 23) extend behind shoulders (20, 21) which are located in the recesses (18, 19). In this way the housing (10) is positioned especially exactly on the jacket rail (9) and avoids components which project over the jacket rail (9).

Abstract: In a lock with a locking cylinder (3), the locking cylinder (3) has a knob (30) on one side and on the other side has a lock channel for insertion of a key (31). The lock has two split hubs (4, 5) on top of one another for triggering a locking element (6). Furthermore, the lock has a positioning element (24) which establishes whether blocking of the locking element (6) produced by the locking cylinder (3) can be canceled by actuation of the split hubs (4, 5). A projection (21) which is located on a plate (20) which interacts with the positioning element (24) establishes from which side this blocking can be cancelled.
