A quick change coupling is provided which is suitable for coupling shafts or tubular members to one another and for coupling a machine tool arbor to a shaft. The apparatus includes a shaft provided with a bayonet receptacle defining one or more bayonet slots. Another elongated member is receivable by the bayonet receptacle and includes one or more detents which are received in locked relation by the bayonet slots. A protective skirt extends from one of the elongated members and encloses a portion of the opposite member. One or more elastomeric members are positioned for engagement with the protective skirt and an elongated member and functions to dampen vibrations therebetween. The elastomeric member may be in the form of a seal to prevent dust and other contaminants from entering the bayonet joint between the elongated elements.
