ABSTRACT:
A handset for telephones and the like has electro-acoustical capsules for hearing and speaking, mounted between an upper housing shell and a lower housing shell of the handset. Each of the capsules is connected to the handset cord by a pair of leads received in cutting clamp connections arranged on the rear sides of the hearing and speaking capsules, the opposed housing shells having projections pushing the leads into the cutting clamps. Preferably, the leads are mounted on a foil having openings for the cutting clamps and the projections, and also openings for guide pins, whereby the leads are guided into the cutting clamps when the upper and lower housing shells are brought together on the leads.
