A slider assembly includes a first slider (20) with a resiliently deformable positioning member (30) secured thereon, a second slider (40) slidably installed on the first slider, and a sliding member (50) slidably secured on the second slider and positioned between the first slider and the second slider. A protrusion (36) protrudes from the positioning member. The protrusion defines a receiving slot (362) therein. A restricting tab (46) protrudes from the second slider. A protrusion (52) protrudes from the sliding member. The sliding member defines a through slot (522) through the protrusion thereof for the restricting tab sliding therein. The sliding member is slidable to disengage the second slider from the first slider.
