Abstract

L'invention concerne un corps allongé comprenant une paire d'ailes opposées flexibles qui s'étendent latéralement à partir de celui-ci, chaque aile ayant une région de fixation angulaire qui s'étend depuis l'extrémité opposée. Une paire de coupelles de préhension opposées se fixent au corps allongé et s'étendent verticalement à partir de celui-ci. Le corps allongé et la paire d'éléments de préhension opposés forment une face de semelle sur un côté et une surface de préhension continue sur le côté opposé. Les ailes opposées flexibles présentent une flexibilité suffisante pour pivoter dans une configuration de serrage.
