At least one adjustable clamp device is disclosed that includes a catch member, a base member, a latch member, and a fine adjustment mechanism and is designed to clamp to a targeted object in a secure fashion. At least one quick release clamp device is disclosed that includes a catch member, a base member, a latch member, and a quick release mechanism and is designed to clamp to a targeted object in a secure fashion and to be quickly removable from the targeted object. At least one method for using the adjustable clamp device is disclosed that includes: wrapping an adjustable clamp device around a targeted object; placing a tool around the adjustable clamp device; squeezing the tool and thereby squeezing the adjustable clamp device around the targeted object; and causing the latch member to operably connect to the catch member in a locked position.

A clip for fastening a pipe to a support, comprising a fixed part, a mobile part, a first joint connecting a first edge of the fixed part and a first end of the mobile part, and a system for holding the mobile part a closed state. The system comprises a lever and a second joint connecting the lever to a second end of the mobile part, and an angled U-shape connected to the second edge of the fixed part, configured to permit the lever and the second joint to pass through the angled U-shape and to permit the lever to be positioned in a folded position against an external face of the mobile part to hold the mobile part in the closed state.

Disclosed clamp rings for fastening a pipe, the clamp ring comprising a strap, a lever and a clip. The strap is attached to the lever, and the lever is attached to the clip, the clip being arranged to grip the strap, and, with the lever gripping the strap, the lever being arranged to push the opposite ends of the strap towards each other. The clamp ring is made in a single piece, the strap, the lever and the clip being connected to each other by breakaway connectors that break when the strap, the lever and the clip are moved relative to each other.

A dual cam lever hose clamp may comprise: first and second cam lever clamps and upper and lower clamp halves. The cam lever clamps may move between a retaining position and release position. The upper and lower clamp halves may form a collar when opposing ends of the clamp halves fasten together via the cam lever clamps. The first cam lever clamp may comprise a first linkage pivotally coupled to a first end of the lower clamp half and a first cam lever pivotally coupled to the first linkage. The second cam lever clamp may comprise a second linkage pivotally coupled to a second end of the lower clamp half and a second cam lever pivotally coupled to the second linkage. The first and second cam lever clamps may comprise cam levers that cammingly engage cam locking surfaces on the upper clamp half to fasten and tighten the collar.
