Abstract
A pacifier or dummy includes a resilient nipple, a guard, and a plug body inserted into the end of the tubular portion of the nipple that is opposite to the mouthpiece. The plug body is carried by a base, which is supported by the guard and is resilient in the direction of the longitudinal axis of the nipple. The plug has projections, which are particularly formed with beveled surfaces and movable along the axis of the nipple. The guard is provided with beveled surfaces adjacent to an opening in the guard. In response to a pull on the nipple, the base is resiliently deformed and the projections of the plug move toward the beveled surfaces of the guard. The plug body has outwardly protruding projections, which are oversize with respect to the clearance between lugs formed on the guard in the opening.
