A protective sleeve for gas bottle valve stems is provided comprised of an elongated tubular body configured to fit on a valve stem. At least one projection extends from an interior surface of the protective sleeve and is adapted to lockingly engage with at least one orifice in an opposing surface of the valve stem whereby the sleeve is prevented from being easily removed from the valve stem upon being placed thereover due to engagement of the projection with the orifice. A tear strip is provided within a side surface of the protective sleeve, whereby a portion of the protective sleeve may be removed to permit disengagement of the protective sleeve. A housing may be provided in the protective sleeve for storage of a washer which may be used to provide a seal between a regulator and the valve stem of the gas bottle. At least one flange extends laterally from the sleeve body and is configured to engage a thumb or finger of the user to assist in placing the protective sleeve upon the valve stem of the gas cylinder by application of downward force, the at least one flange positioned along the longitudinal extent of the protective sleeve between the ends of the protective sleeve.
