The invention relates to an improved fastening mechanism used in a decorative light bulb series. The improvement according to the invention includes a light bulb socket with two opposite lugs formed on the peripheral rim of the top end thereof and a housing provided on the side surface thereof with a locating post having tapered cross sections. When the light bulb socket is placed into the housing, the locating post extends into the passageway defined by two lugs to form a firm engagement between the socket and the housing. To detach the light bulb socket from the housing, just apply a force large enough on the bottom surface of the locating post. The socket can easily get out of the constraints exerted by the lugs without any damages to either the socket itself or the housing. Hence the assemblage and detachment can be repeatedly conducted.
