ABSTRACT OF THE DISCLOSURE An adjustable fastener for interconnecting a first part and a second part, comprising: an elongate rack adapted to be secured to the first part and having a row of teeth; and a slider adapted to be fastened to the second part and movable on and along the rack for locking engagement therewith at a selected position. The slider comprises a housing having a longitudinal channel for passage therethrough of the rack, and a groove in that surface of the top plate of the housing which faces the channel. The groove extends transversely of the channel. A locking member is slidably held within the groove for locking engagement with one of the teeth. An elongate spring extends in and along the channel for normally retaining, when in a relaxed state, the locking member in locking engagement with said one of the teeth. The locking member is movable along the groove out of locking engagement with said one of the teeth against the force of the resilient means. The fastener has a reduced susceptibility to functional defects caused by penetration of fibrous dust or the like into the slot guiding the locking member.
