ABSTRACT:
A detably attaching mechanism for a cup of a lubricator or a filter used with an air-actuated device comprising such cup containing therein a quantity of lubrication oil or filter elements, means to supply a quantity of lubrication oil from the cup into an air stream flowing from an inlet to an outlet or to introduce the air stream through the filter elements contained within the cup, a cover mounted on the cup and a protective cylinder mounted around the cup, characterized by that the protective cylinder is provided on its outer periphery with a locking piece adapted to have its front or top end being outwardly tilted away from the outer periphery of the protective cylinder by depressing its rear or lower end and this locking piece is mounted with interposition of an elastically flexible leg on the outer periphery of the protective cylinder and that the cover is provided in its outer periphery with receiving means adapted to receive the front or top end of the locking piece upon completion of attachment of the cup and the protective cylinder to the cover and thereby to prevent rotation of the cup and the protective cylinder relative to the cover.
