Abstract:
An expansion clamping assembly, comprising:an annular shaped band having first and second ends; said first and second ends each being bent over inward portions of the band and joined at given locations therealong respectively forming first and second elongated guide openings; said first and second bent over ends each having guide surfaces on respective sides thereof which are skewed relative to side surfaces of said band adjacent said skewed surfaces; said band being arranged so that the end portions thereof containing said guide openings overlap one another in a lateral direction to arrange the first and second skewed surfaces to be in slidable engagement with one another; an elongated threaded member extending through said guide openings having a portion thereof resting against one of said side surfaces, said threaded member extending beyond the remaining side surface; and a threaded nut threadly engaging the elongated threaded member which, when tightened causes the first and second engaging skewed surfaces to slide along one another thereby reducing a total width of the overlapping ends while expanding an outer circumference of said band.
