A fastener for connecting two components together comprises a bolt having a head and a shaft extending integrally and downwardly from the head, an elastic member coiled around the shaft and a shell receiving the elastic member and the bolt therein and keeping the elastic member coiled around the shaft. The shell encloses the bolt and the elastic member therein to form the fastener as a single unit. The shell has a top wall against which the head of the bolt abuts and a bottom wall through which a lower portion of the shaft extends. The top wall defines a through hole to expose the head of the bolt. The elastic member is compressed between the bottom wall and the head.
