A linear motion guide assembly (10) comprises: a tubular housing (12) provided with a longitudinal internal cavity (14) for accommodating a linear drive, a longitudinal slit (16) between the longitudinal cavity (14) and an outer face (18) of the housing and a pair of longitudinal side grooves (24) formed on the outer face (18) of the housing on each side of the longitudinal slit (16), each of the side grooves (24) having opposed concave side wall portions (42). The longitudinal slit (16) and side grooves (24) are covered by a cover band (22). The cover band (22) is provided with a pair of longitudinal resilient protruding portions (28) each arranged so as to be releasably engaged and clamped in a respective one of the side grooves (24) of the housing. A slider (20) slides or rolls on a longitudinal track of the housing (20) between two end positions. The slider (20) extendes through the longitudinal slit (16) to be coupled to the linear drive. The slider (20) has two longitudinal ends and is provided with guiding means (30, 32) for lifting a portion of the cover band (22) between the longitudinal ends of the slider (20) on a path out of engagement with the side grooves (24). Each longitudinal resilient protruding portion (28) comprises a pair of parallel ribs (34) spaced apart from one another, each rib (34) having a convex external face (36) facing away from the other rib (34) and an internal face (38) facing the other other rib (34). |
