ABSTRACT:
A piston hank has an openable loop which is defined by a substantially U-shaped portion of a fastener body and part of a closure link which is pivotally connected to the fastener body. In a locked position, the closure link bridges the shanks of the U-shaped portion of the fastener body. The closure link comprises a spring actuated locking pin which is displaceable in a substantially straight groove and which, in the locking position, protrudes from an end of the closure link and which cooperates with a recess or hole formed in the fastener body. A release member is provided for displacing the locking pin into the closure link against spring action to a release position, in which release position the locking pin is disengaged from the recess or hole and the closure link can be swiveled open.
