An apparatus for permitting an immediate release of safety belts of vehicles allows passengers to escape in case of emergency or in circumstances dangerous to the passengers. The apparatus has a series of sensors (3, 4, 5, 6, 7, 8) connected to a distributing station (9), an auxiliary battery (13), relays (10 and 14) and a microgearmotor (16) which can pull cables (17) that are connected to opening elements which permit the belt fasteners (2) to be disconnected. The microgearmotor (16) may be replaced by a microcompressor acting with a piston to provoke the traction of the cables (17). According to another possible variant the microcompressor acts directly on hydraulic or pneumatic ducts each of which operates a micropiston which is provided in the belt fastener (2).
