ABSTRACT:
A releasable fastener for an album to permit insertion and removal of pages between the covers. The fastener has a pair of strap anchors each attached to one of the two covers and a strap passing between the anchors via aligned apertures in the covers and album pages. Each strap anchor is in the form of a channel in which the strap is a snap fit so that the strap is releasably locked into the channel and is restrained from longitudinal displacement by inter-engaging formations on the base of the channel and the opposing surface of the strap.
