A clamp setting tool secures a hose clamp having a pre-clamped state where a catch tab engages a stopper tab, and a clamped state where the catch tab releases from the stopper tab. The clamp setting tool includes first and second head elements having respective first and second notches formed therein, the second notch positionally corresponds to the first notch. The first and second notches receive the catch and stopper tabs. A stop mechanism is connected to one of the first and second head elements. The clamp setting tool moves the first and second head elements between an open position where the hose clamp is maintained in the pre-clamped state and a closed position where the first and second head elements move the hose clamp to the clamped state. The stop mechanism prevents movement of the first and second head elements from the open position toward the closed position.

A wire gripper 10, which is lightweight and can perform a work for holding a gripped state of a tensioned wire easily and safely, is provided with a stationary gripping body 12 having a wire-like body pressing-down portion 24; a swinging member 14 swingably attached to the stationary gripping body by a supporting shaft 70; a movable gripping body 16 having a wire-like body holding portion; a connection member 18 swinging the swinging member; and a swinging member restricting portion 20 restricting an amount of swinging of the swinging member, wherein the stationary gripping body 12 is formed with reinforcing portions 32 and 40 in a region in which the supporting shaft is attached, and a wire-like body W clamped does not disengage from between the movable gripping body 16 whose movement amount is restricted by the swinging member restricting portion 20 and the stationary gripping body 12.

A parallelogram wire gripping apparatus (150, 250) is disclosed. There is a pair of distal arms (151, 152, 251, 252) and a pair of proximal arms (153, 154, 253, 254). The distal ends of the distal arms are pivoted to each other and are shaped to form a wire clamp (165). Each proximal end of the distal arms is pivoted to a corresponding distal end of the proximal arms. Each proximal arm is pivoted together at a midpoint thereof. A spring (130, 230) urges the wire clamp closed. A wire gripping jaws arrangement (165) incorporating fasteners (171, 172, 173) is also disclosed. A wire strainer incorporating two grippers (141, 142), a chain (144) and a winch (143) is also disclosed.

A binding machine includes: a first body part; a second body part having a curl guide and a twisting shaft that holds and twists the curled wire; and an elongated connecting part connecting the first body part and the second body part. The curl guide includes a first guide part and a second guide part projecting in a first direction from the tip end of the second body part and disposed with a prescribed gap therebetween in a second direction orthogonal to the first direction. The first body part and the second body part are disposed such that a virtual axis line is inclined toward the axis line of the twisting shaft, the virtual axis line connecting an intermediate position in the prescribed gap and an intermediate position in the lateral direction of the connecting part at the connection end of the connecting part with the first body part.

A tension clamp (19) includes a band (20) surrounding an object to be fastened and a buckle (21) arranged on the inner band end portion (22) and surrounding the band (20), with the outer band end portion (23) extending through the buckle (21). A tool for mounting the tension clamp includes a holding device for holding the buckle (21) along with the band (20) surrounding the object to be fastened, a tensioning device for tensioning the band (20) round the object to be fastened by applying tension to the outer band end portion (23), a locking device (50) for locking the buckle (21) on the band (20), and a severing device for cutting off excessive band length. The locking device (50) has plier jaws (54) adapted to be inserted into lateral windows (25) of the buckle (21) for deforming side edge portions (24) of the other band end portion (23).

Embodiments of the invention are directed to adjustable closure devices. One embodiment has a strap, a connector attached to a strap end, a chafe mounted on the strap behind the connector, and a hinged handle on the chafe. The chafe has a two outer bars and a central bar, these bars defining strap through-paths. The strap end-region has path segments arranged, directionally from the strap's central region toward the strap end at the chafe, or, in embodiments that configure the strap as a pulley, at the connector. An adjustable length region of the strap spans between the chafe and the connector. An elevatable handle configuration allows a user to pull the chafe to which it is connected along the strap, away from connector. As the chafe moves along the strap, the strap can transition between a large circumference configuration and small circumference. Some embodiments have a strap friction-locking mechanism associated with the handle and the chafe.

A method of operating a pre-opened pre-positioned clamp, the clamp being operable between an open and a closed position. The method comprises releasing the clamp from the open position using a tool head (201), making measurements of a movement of the tool head resulting from the releasing, recording data relating to the measurements, determining a frequency content of the data, and, on the basis of the determined frequency content, determining whether the clamp has moved to the closed position.
