The present invention relates to a removable, self-locking chimney cap which is screwless. The chimney cap comprises a stationary member and a removable member removably mountable to the stationary member. The stationary member comprises a base plate adapted to be secured to the end of the chimney or venting system and defining an opening, and a first tube mounted to the base plate around the opening. The removable member comprises a second tube adapted to slide over the first tube and a cap mounted to the second tube, the first and the second tubes comprising a pin and a corresponding bayonet slot adapted to receive the pin, whereby when the second tube slides over the first tube, the pin is received by the bayonet slot and locks the removable member with the stationary member. Such a chimney cap may be manually locked and unlocked in a single step, without the use of tools.
