         9 . The protective device of  claim 7 , comprised of a plastic resin material. 
     
     
         10 . The protective device of  claim 7 , wherein said housing for storage of said washer has a portion adapted to physically engage with an interior hole of said washer to hold said washer in place within said housing. 
     
     
         11 . The protective device of  claim 7 , wherein said housing for storage of said washer includes a removable cover to close said washer within said housing. 
     
     
         12 . The protective device of  claim 7 , comprising multiple projections. 
     
     
         13 . A protective device for use in connection with a four-sided valve stem for gas bottles, said valve stem having a gas port;
 said protective device comprised of a unitary molded tubular body comprising four sides and having opposing open ends;   one or more projections extending from an interior surface of said protective device and adapted to physically engage with a portion of an opposing side of said valve stem, whereby said protective device is prevented from being easily removed from said valve stem upon being placed over an end of said valve stem and moved into sliding engagement therewith due to engagement of said at least one projection with said portion of said opposing side of said valve stem;   said body being of such length as to extend along at least a portion of the length of said valve stem, said tubular body having such size and dimension such that sides of said tubular body are adjacent to opposing sides of said valve stem in protective relationship thereto and covering said gas port in said valve stem when said protective device is placed over said valve stem in sliding engagement therewith;   a tear strip provided within at least a portion of a side surface of said protective device, whereby at least a portion of said side surface of said protective device may be removed by tearing said tear strip so as to permit disengagement and removal of said protective device from said valve stem;   said device further including at least one flange surface extending laterally outwardly from said device along a plane transverse to a longitudinal axis of said unitary molded tubular body; and   further including a housing for storage of a washer seal, said housing extending laterally outwardly along a plane transverse to a longitudinal axis of said unitary molded tubular body.
