Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
One-piece self-locking flat clamping band provided on its upper surface within its whole width with an operating toothing with a negative inclination of front sides of teeth, the band terminating on one end by a tail part and on the other end by a head with an opening for the introduction of the tail part of said band, the head being parallel with the band, a catch being provided on said head beyond the internal part of the head, a toothing with negative inclination of the front sides of teeth corresponding to the toothing on the band oriented in the opposite direction to that of said operating toothing being provided on the lower surface of said catch, both said toothings when mated forming a lock, said catch and that of the corresponding toothing situated thereon each having at least three teeth and having the same width as the band, the catch with its mating toothing being tilted toward the band so that after the lock has been formed the catch exerts a substantial pressure on the operating toothings.
Claim 2
Dependent Claim
178 words
