The detent means for a heat sink is provided thereon with an elastic member in connecting with two side clamp holders, the elastic member is bent to render the bending area to be the force bearing point which is communicating in force with the two side clamp holders, the thickness of a lateral arm between the bending area and one of the two side clamp holders is gradually reduced toward the side clamp holder; the lateral arm of the elastic member can be slightly bent and fixed in shape by the force exerting on the elastic member, after being fixed in shape, the elastic variable thereof is fixed for firmly holding by clamping; the detent means can prevent cracking of the main body of the heat source due to an overly large clamping force, and can largely increase the extent of application of the detent means in mating with any of various main bodies of heat sources and heat sinks of different thickness.
