A cap to be placed on the nozzle of a caulking cartridge, for example, loaded in a caulking gun for preventing discharge from the nozzle and sealing it. The cap comprises an elongate hollow body closed at its front end and open at its back end for placement of the cap on the nozzle with the nozzle received inside the body. An elongate plug extending rearwardly within the body from the front end thereof enters the nozzle on placement of the cap on the nozzle for plugging the nozzle and preventing discharge therefrom. The cap may be clipped to the caulking gun when caulking is being dispensed from the cartridge via the gun.
