ABSTRACT:
An improved fluid connector for garden use includes a tube body, a resilient retainer and a sleeve associated therewith. The tube body includes a plurality of holes for accommodation of a locking hook respectively and the resilient retainer is peripherally equipped with several pairs of vertical flexible ribs with an expansion space defined therebetween. On an inner wall of the sleeve, a plurality of push protrusions is disposed and is positioned in relationship with the vertical flexible ribs respectively so that, as the sleeve is pushed downwardly, the flexible ribs may be forced to deform and produce an reactive force that can instantly push the push protrusions of the sleeve back to their original place when the sleeve is free of an external force.
