Abstract: A cam operated clamp (10) having a housing (11, 51) which changes its effective diameter due to the rotation of a cam (40) includes a stop (33, 55, 60) for stopping cam rotation when the clamp (10) is tightened. The cam pin (40) has a stop lug (45, 49) formed on one end, which abuts with a stop tab (33, 55, 60) formed on a cam journal (27, 29, 63, 64, 65, 66, 76, 78, 82, 84). When the stop lug (48, 49) abuts with the stop tab (33, 55, 60) as the cam (40) is rotated in a first direction, the clamp is in a maximum clamping position and cannot be rotated beyond the tightened position to a position wherein the clamp is loosened.
