A slot (6) which is narrower at the distal end (4) than over the remainder of its length reaches from the tip (4) to the region of the proximal end portion (3). Both in the principal portion and in the final portion there are pairs of through-holes (10, 11, 12) as transverse and diagonal bores. <IMAGE>
