A filter pump for a pool includes, a motor, a filter, a water intake connecter and a water outlet connecter for combining water pipes. The water intake and outlet connecters are respectively fixed with a connector having male threads outside and a recessed stepped surface inside to make up a receiving space between the connector and the water intake or the water outlet connecter. The water pipe has its end formed with two annular projecting ribs for fitting a rotatable locking cover with female threads therein. After the water pipe is fitted with the water intake or the water outlet connecter, the locking cover is threadably mounted on the connector, letting the water pipe inserted in the receiving space and closely pressed by the locking cover.
