Abstract: A compression cap is provided with a first connector and a fitting is provided with a second connector. The first connector locks onto the second connector to hold the cap to the fitting before the clamp is crimped. The first connector is a hook that extends outwardly from a first end of the compression cap, and the second connector is a protrusion on the fitting. The first and second connectors can be secured with a bayonet connection before the cap is compressed. The cap may also include at least one inward deformation that engages the outer surface of the pipe as the cap is slid onto the pipe, creating friction between the pipe and the cap and thereby preventing the cap from falling off the pipe prematurely.
Abstract: A one-piece unitary compression clamp for securing a pipe or tube on a fitting. The clamp may include at least one inward deformation that provides an interference fit between the clamp and the pipe or tube. Consequently, the clamp cannot fall off the pipe or tube before being permanently crimped, and the fitting is prevented from falling out of the tube. In a second embodiment, the clamp includes an ear for crimping the clamp to the tube, and a tongue within the clamp and overlying the mouth of the ear to provide uniform compression around the entire tube. In a third embodiment, the clamp includes stop tabs that hold the pipe at a stand-off from the end of the clamp.
