A device for holding an ear defender includes a housing with a space therein to accommodate a loop which forms part of a supporting member for an ear defender. The space is defined by a bottom wall, a rear wall, and a front wall, the front wall having notches to receive part of the supporting member connected to the loop. The loop is provided with two journalling parts which are arranged in line with each other and which are arranged in a groove on the inside of the front wall to thereby provide a journalling axis for the supporting member. An aperture is formed in the housing to extend through the bottom wall, and a central pin is positionable in the aperture for the purpose of affixing the device to a helmet. A lever is pivotably journalled with one end in the space for housing near the inside of the rear wall and the other end arranged to receive a transverse spring section of the loop. The spring section is arranged to press against the lever which is adapted to be moved through a dead center condition between two positions, the supporting member being thus pivotable about its journalling axis between two distinct positions.
