A PTC device which comprises a housing (1); two metal members (2, 3), each of which comprises an elastically deformed retaining element (22, 32) inside the housing and a terminal element (21, 31) outside the housing; and (3) a PTC component (4) which is removably retained within the housing by elastic recovery forces of the retaining elements. The PTC component includes a laminar resistive element (43) composed of a PTC conductive polymer, and two electrodes (41, 42), each in contact with one of the retaining elements. The PTC device is particularly useful for providing a connection, accompanied by overcurrent protection, between two wires, e.g. in loudspeaker assemblies.
