A seat belt buckle for use with a tongue 16, includes a frame 10 in which is mounted an ejector 20, operable by an ejector spring 22. Insertion of the buckle pushes a retainer 30 e.g. a ball, down a ramp 26, against the action of a retainer spring 32. When the tongue has been inserted an adequate amount, the ball 32 engages an aperture 18 in the tongue 16 to retain the tongue 16 in the locked condition as shown in figure 4. |
