A clamping sleeve is of generally cylindrical shape with a hollow interior and comprises an upper crown, a lower crown, and a tubular sidewall. The upper crown is positioned at an upper end of the clamping sleeve. The lower crown is positioned at a lower end of the clamping sleeve. The tubular sidewall is positioned between the upper and lower crown and includes one or more corrugations that utilize spring like principles such that pressure applied to the external surface of the tubular sidewall circumferentially flexes the clamping sleeve in order to reduce the diameter of the clamping sleeve and apply a clamping force to an object within the clamping sleeve. The clamping sleeve may be utilized in a work support that includes a plunger positioned within the clamping sleeve, wherein a pressurized flowable medium provides pressure to the exterior of the tubular sidewall thereby causing the clamping sleeve to apply a clamping force to the plunger.
