Removable ice screw securing device equipped with a quickdraw
摘要:
The invention relates to a securing device to be screwed in having an attachment lug equipped with a movable fixing means designed to prevent any twisting effect of the quickdraw when rotation of the ice peg takes place. The fixing means is formed by a cylindrical stud mounted rotating freely on a spindle securedly affixed to the attachment lug. The stud acts as operating handle for driving the securing device in rotation whereas the quickdraw remains permanently attached to the lug.
