ABSTRACT:
A tensioning lever is mounted on one part of the shoe. A tension loop is mounted on another part of the shoe and adapted to be hooked into the tensioning lever. The tensioning lever can be moved along a rack to tension the fastener and is restrained by releasable means against being pulled back.
Before a retensioning of the fastener, the latter should not be relieved from tension entirely. For this purpose, the tensioning lever cooperates with a ratchet mechanism for tensioning the fastener. The ratchet mechanism comprises a driver which cooperates with the rack and which consists of or is adapted to move with the tensioning lever.
