The frame and the loudspeaker have ratchet devices so that the speaker on moving w.r.t. the frame can engage the frame and after rotation can be released from the frame. The speaker's cage has one or more spring arresting tongues (1-3) with hooks (4-6). The frame has holes with edges to hold the hooks and guide slots (11-13) in which the hooks can slide after rotating cage and frame relatively so that the cage can be disengaged from the frame. Webs (14-16) acting as breakage points lie between the openings and the guide slots.
