Abstract
A fastener or closure is formed of flexible material having a portion which is deformable from a first fixed configuration to a second configuration. Two projections are spaced apart one from the other when the deformable portion is in one of its configurations, and are sufficiently close when the deformable portion is in its other configuration to prevent removal of a fastened article from the fastener. In this manner, both easy opening and secure closing are obtained with the closure.
