In a normal three-point automatic safety belt system the webbing is generally led from an end fitting secured to the vehicle over a guide fitting to a belt takeup means which is disposed on the same side of the vehicle seat as the guide fitting. Along the webbing a slide buckle can be displaced which can be releasably locked to a belt lock which is secured on the opposite side of the vehicle seat to the vehicle. When the slide buckle is inserted into the webbing it divides the latter into a lap portion and a shoulder portion. To secure a child's seat on the vehicle seat by means of such a normal three-point automatic safety belt system by the lap portion bearing on the child's seat the safety belt system is equipped with an additional clamping means which permits tightening of the lap portion but offers resistance to loosening of the lap portion. The clamping means can be formed by a securing slide buckle with clamping means which is arranged additionally to the normal slide buckle displaceably along the webbing and adapted to be locked selectively instead of the normal slide buckle in the belt lock, or it can be formed by a clamping member which to produce a clamping effect can be brought into engagement with the normal slide buckle.
