Abstract
Abstract Exchangeable gripper element for sports shoes, especially studs for football boots, with a threaded extension which can be inserted in an orifice of the outsole of the sports shoe, the threaded extension having a steep thread, in the form of one or more helical ribs or grooves, on its otherwise cylindrical outer surface, and a locking element in the form of a projection or a recess being provided on the threaded extension and/or the support face of the gripper element, which can be snapped into a part of the outsole which is of complementary shape thereto. This provides a gripper element which can be screwed in quickly and is secured against undesired loosening in use.
