Abstract: A device for adjustable attachment of a strap includes an injection moulded element forming an aperture therein. A cross bar forms an integral part of the element and extends across the aperture. An injection moulded plate has an opening and is integral with two spring legs diverging from an edge of the plate. The plate is mounted in the element which forms a cover at one side of the plate, and is displaceable in the element with the free ends of the spring legs engaging the element to bias an edge of the opening, substantially parallel to the cross bar, against a strap passed around the cross bar.

Abstract: Buckle for a safety belt, particularly a children's belt, comprising a buckle housing (10) and a lock tongue (13) constructet to be connected each to one strap part. The lock tongue is insertable into a guide (15) in the buckle housing which has a latch member (19) spring biased to lockingly engage the inserted lock tongue, and an opening member (20) to be operated manually for switching the latch member from an engaged position to a disengaged position against the spring bias, said two members consisting of one and the other, respectively, limb of a U-shaped element (17) which is pivotally mounted in the buckle housing (10) to switch about a transverse axis (21) with the limbs extending along the guide (15) towards the insertion opening (12) for the lock tongue (13) which at the insertion into the buckle housing can be pushed in between the limbs.
