A buckle for safety belts for vehicles comprises a belt locking member and a buckle body having an opening for the insertion of the locking member. The insertion opening is defined by two stationary side plates and two locking hooks pivoted to the buckle body and cooperating with the two longitudinal edges of the locking member, which locking hooks are adapted to be swung against the action of a spring mechanism into locking position by the locking member upon insertion thereof in the buckle body, in which locking position the locking hooks engage in recesses formed in the two longitudinal edges of the locking member. The locking hooks, which under the action of the spring mechanism tend to expel the locking member inserted in the insertion opening of the buckle body, cooperate with a spring-loaded latch which in the locking position engages the locking hooks and which is adapted, upon release of the buckle, to be moved out of the engagement with the locking hooks by an operating member against spring action. This latch is movable substantially at right angles to the two side plates of the buckle, extends between the side plates, and cooperates with recesses which are formed in the side plates and serve as guides for the latch. The operating member is an arm which is pivoted to one side plate of the buckle body, is formed as a push button, and cooperates laterally of the axis of pivotment with the latch to move it when the arm is swung.
