The present invention discloses a Christmas lamp with a lamp core pull-out prevention structure and a forming process therefor. A lamp core is stably mounted so that a good pull-out prevention effect can be achieved, and the forming process is simple so that automatic production can be realized. A technical scheme consists in that the Christmas lamp includes: a lamp holder, a lamp core and a lamp shell. The lamp holder is connected to the lamp shell, and the lamp core passes through the lamp holder and is located in the lamp shell. The Christmas lamp further includes a fixing ferrule. The lamp holder is internally provided with a resilient clamping sleeve for radially clamping the lamp core, and the fixing ferrule is provided over the resilient clamping sleeve. When the lamp holder is mounted and connected to the lamp shell, the fixing ferrule is axially abutted between the lamp holder and the lamp shell, and the fixing ferrule radially locks the resilient clamping sleeve, such that the resilient clamping sleeve locks the lamp core. The present invention is applicable to the technical field of decorative lamps.
