Couplings, disconnectible.-An external band d with horizontally-extended slots for locking an electric incandescent lamp in its holder is retained by studs f engaging the horizontal parts of the slots. The band is rotated to lock the lamp without the use of a key. According to the Provisional Specification, the band may have inclined slots to take the lamp pins, and separate inclined slots for the studs f, and these slots may be complicated by horizontal, vertical, or inclined extensions; the studs f may be replaced by stops, or the screw - thread provided on the holder for the shade-ring may keep the band in place.
