<p>A coupling to connect pipe, including lengths of pipe, valves, hoses, and pipe and hose fittings, includes a body to closely receive the end portion of the pipe to be coupled and jaw members to secure the pipe to be coupled in the coupling. The coupling includes an internal groove extending at least partially around the pipe end portion when received in the coupling. The jaw members are mounted to the coupling body to establish a fulcrum for rotation of each lever jaw member about the fulcrum between an engaged position and a disengaged position with respect to the pipe end portion when received in the coupling body. At least a portion of the jaw members are positioned in the coupling internal groove. Additionally or alternatively, jaw members may be provided adapted to slide along the inner groove in the coupling body to move between a position spaced radially from the received pipe to allow the pipe to move into or out of the coupling body and a position securing the pipe in the coupling body. An insert may be provided to lock the jaw members in position. The ends of the pipes to be joined can be configured for use with the coupling by the attachment of special rings to the end portions of the pipes.</p> |
