This invention relates to improvements in v sanitary attachments fortelephone mouth- 7 pieces-and its primaryobject is to provide a simpleand'relatively inexpensive device'provided with means which make it possible to V attach the device to 'mouthpieces of various diameters, such as are used in telephones of the ordinary type, telephones of the bracket type and all kinds of speaking tubes for house 1Q telephones and the'like.

Another obj ect of this invention is toprovide a relatively inexpensive device adapted to be'made from a single blank h'avingmeans for quickly attaching it to a telephone mouthpiece andvmeans for retainin a capsuleof a phones and like apparatus are eliminated. j

A further objectis-to provide a device of the characterospecified adaptedto-be held within the mouthpiece of a telephone or like instrument,- withoutinterfering with the operation thereof.
