An electric lamp having a base at one end, in particular a high-pressure lamp, having a lamp bulb which is sealed in a vacuum-tight manner, said lamp bulb being surrounded by an envelope part, a base having electrical connections bearing on one side the outer bulb and on the other side the envelope part, having the following features: a) the base has a base insulator which is produced from an insulating material and has a central opening in which the outer bulb is accommodated without cement; b) the base insulator has a circular, radially projecting segment having an upper and lower plateau which is associated with the base; c) on the base side the envelope part has a circular opening having a radially projecting edge which has a lower and an upper contact surface in relation to the base, the lower contact surface of the edge matching the upper plateau of the circular, radially projecting segment on the base insulator; and d) the envelope part is fixed to the base by means of a cement-free, mechanical retaining mechanism.
