A slide fastener part, such as one side of a coil zipper, includes a sequence of fastening element locations 30A, some of which are provided with a closure element 35A. Several of the fastening elements 35A include an abutment portion 39A for selectively interlocking with an engaging portion 39B of an opposing fastening element 35B of a similar slide fastener part such that the fastener parts can be attached and detached by movement of a slider. At other fastening element locations 30A of the slide fastener part, abutment portions 39A are omitted, defining a region where the attached slide fastener parts are relatively easily separated. A slide fastener including both slide fastener parts is also claimed, and each slide fastener part may carry a flexible strip, distal ends of which abut over the slide fastener parts. Also disclosed is a life preserver system including a cover and an inflatable unit housed therein, in which the slide fastener is arranged to cover an opening in the cover such that the bladder is released from the opening by separation of the slide fastener parts at the weakened region.
