ABSTRACT OF THE DISCLOSURE An attachment device in the form of a bearing hous- ing and an arm extending out through an opening in the hous- ing. The arm is supported in a bearing support in the hous- ing and serves to carry, at the end opposite the housing, an ear muff to move with a rocking motion between a station- ary rest position and a position wherein the ear muff exerts a pressure around the wearer's ear. A separate spring com- ponent, preferably annular in form, is rotatably supported in and prestressed to bear against, on one side, an adjus- table spring support, which is located inside the housing and remains stationary during the rocking motion, and, on the opposite side, the end of the arm located inside the housing. By this arrangement there is exerted on the said end of the arm a controlled force directed away from the spring support for stabilizing the arm in its two positions. The spring support may consist of a rocker, the position of that part of the rocker in which the spring component is supported being adjustable against an adjusting means with respect to the nearer end of the arm to permit alteration of the prestressing of the spring component. The adjusting means consists of a cover with an annular collar of thick- ness varying along the extent thereof. The collar rests against the inside of the ring flange of a base, which is rotatable with respect to the said adjusting cover.
