<p>The present invention provides a fastener adapted to be secured to a first member for fastening a keeper secured to a second member. The fastener comprises a base member, a sleeve member connected to the base member, and a slide member received within the sleeve member to be extended or withdrawn. The sleeve member is included with an opening into which a cam mechanism is received for rotatable movement. A cam member is also provided extending from the cam mechanism and into a cam opening provided in the slide member. The fastener also includes a turning member which is adapted to rotate the cam mechanism so as to move the cam member within the cam opening in order to extend or withdrawal the slide member. The fastener may also include a biasing member confined within the base member in order to bias the sleeve member relative to the base member as the slide member is fastened with the keeper. In addition, the fastener may be adapted for increasing the amount of extension or withdrawal of the slide member. Further, the fastener may be adapted for retaining the cam mechanism within the opening provided in the sleeve member. The fastener may also include a cam mechanism of increased strength.</p> |
