A telephone adapter for use with a telephone terminal unit having a plurality of contacts each of which is connected with a telephone wire. The adapter has a housing provided opposite an open side thereof with a transverse wall formed with a plurality of apertures therethrough. The number of apertures corresponds to the number of contacts on the terminal unit with which the adapter is to be used. In the interior of the housing is located a plurality of axially compressible helical contact springs each aligned with one of the apertures and so dimensioned as to frictionally engage a contact pin which is pushed through a respective aperture from the outer side of the housing. A plate member of insulating material is received through the open side in the housing and has at one major surface which faces the springs projecting pins which are each conductively received in an adjacent end of one of the springs, and on the opposite major surface the plate member has contact strips which are each conductively connected with one of the pins and which, when the housing is connected by means of connecting means provided for this purpose with the terminal unit, each engage one of the contacts on the terminal unit.
