A connecting device for an automobile seat belt including a tag, and a buckle comprising a base and a slider block slidably fitted with each other. The base comprises at least two latches slidable in directions substantially at right angles to the direction of insertion of the tang and urged away from each other by means of a spring fixed at the center of the base and integrally constructed with a spring forcing the tang out of the buckle when the former is released from the latter. The slide block is provided with a guide hole engaging the latches of the base and having guides for moving the latches toward each other in response to a movement of the slider block. The tang has a pair of guides for moving the latches toward each other in response to insertion of the tang into the buckle and a pair of anchoring portions adjoining the pair of guides for the latches. The device including the buckle and tang is lengthwise shorten and compactly constructed, which is particularly advantageous for a passive seat belt. |
