An adjustable fastener for interconnecting a first and a second part of an article includes a flat hollow sleeve (1) having a first connecting portion (5) for attachment to the first part, a plug (8) having a second connecting portion for attachment to the second part, a flat body (9) slidably received in a longitudinal guide channel (4) in the sleeve (1), a locking member (16) slidably held within a transverse guide groove (6) in the sleeve (1) and having a pusher head (18) at an end thereof, and at least one locking projection (19) releasably engageable with one of a row of teeth (12) on the plug body (9) for locking the plug (8) in position against displacement, and a spring (23) held within the sleeve (1) for normally retaining the locking projection (19) in locking engagement with the one tooth (12) and keeping the pusher head (18) to project outwardly of the sleeve (1). The locking member (16) is movable along the guide groove (6) to disengage the locking projection (19) from the one tooth (12) against the force of the spring (23) when the pusher head (18) is depressed. |
