  • Patent number: 7509712
    Abstract: A device for the connection of a band to a further part. The device has a casing (3) fixable to the band, forming a unit with the band and receiving a locking element (1). The locking element (1) in the casing (3) is mounted about an axis (12) so as to be pivotable from a retaining position into a release position and back. The axis (12) is oriented transversely to the longitudinal extension of the band and in parallel to the band plane. The casing (3) is provided, at the front side, with an opening (9) for inserting a retaining clip arranged at the further part. The retaining clip can be brought into a form-fitting connection with the locking element (1) which is in the retaining position.

  • Patent number: 7451528
    Abstract: In a device for the connection of an end part (5) of a band (1) to a rigid part (2), in particular a watchband to a watch casing, a pin (3) arranged at the end part (5) of the band (1) and extending, with its longitudinal axis, transversely to the longitudinal direction of the band (1) can be engaged with at least one recess (7) of the rigid part (2). In order to attach the band (1) to the rigid part (2)—even if said part has different shapes—with as little clearance as possible, the device is characterized in that the pin (3) is movable into different positions relative to the band (1) in a direction transverse to its longitudinal axis and can be fixed to the band (1) in these positions which it can assume relative to the band (1).
