Abstract: A belt lock, particularly for the vehicle safety belts, comprising a lock housing (10) and a lock tongue (11). The lock housing forms a guide between two plates (12, 13) for receiving the lock tongue in the lock housing, and an ejector (23) is provided in the lock housing. The ejector can be displaced against spring bias by the insertion of the lock tongue into the guide. The lock housing is provided with a manually operable latch mechanism comprising a ball (21) which can be displaced in an aperture (22) in one plate and is spring-biased to engage a seat formed by an aperture (27) in the other plate (12) to be received in this position in an aperture (35) in the lock tongue with the center of the ball located in the aperture in the lock tongue while the lock tongue is retained against withdrawal from the lock housing. The latch mechanism also comprises a manually operable member (77) for displacing the ball against the spring bias.
