Claim:
An assembly comprising a plug and a heating element for a diffuser device for volatile substances, wherein the plug comprises a body in which conducting poles for connection to an electrical socket are mounted, and the heating element comprises a body in which at least one electrical heating resistance connected by electrical wires to the poles of the plug is disposed and said body of the heating element is destined to be disposed near to or in contact with a support impregnated with volatile substances to be diffused, characterized in that the assembly further comprises at least one connector having a first end attached to said body of the plug and a second end attached to said body of the heating element, said connector configured with a breakable weakened part, so as to avoid relative movement of said body of the plug with respect to said body of the heating element until the weakened part is broken, which causes the body of the plug and the heating element to no longer be connected through the connector.
