An adjustable fastener for interconnecting a first and a second part of an article includes a flat hollow sleeve having a first connecting portion for attachment to the first part, a plug having a second connecting portion for attachment to the second part, a flat body slidably received in a longitudinal guide channel in the sleeve, a locking member slidably held within a transverse guide groove in the sleeve and having a pusher head at an end thereof, and at least one locking projection releasably engageable with one of a row of teeth on the plug body for locking the plug in position against displacement, and a spring held within the sleeve for normally retaining the locking projection in locking engagement with the one tooth and keeping the pusher head to project outwardly of the sleeve. The locking member is movable along the guide groove to disengage the locking projection from the one tooth against the force of the spring when the pusher head is depressed. |
