self-locking member 4 is positioned on the said S-shaped body 2,
and the other end 42 of the self-locking member 4 is locked on the
hook-bill 22 by means of an elastic force so that the two
hook-bills 20, 22 are locked. Unlike the first embodiment, here the
hook-bills 20, 22 are locked into the notches (the notches 204, 224
as illustrated in FIG. 6). Correspondingly, the self-locking
members 3, 4 do not necessarily include the arcing portion forming
the recess.
[0026] Referring to FIG. 5, it is a perspective view illustrating
the self-locking member of the hook in a free situation according
to the second embodiment of the present invention. As illustrated

openings 220,222 are arranged in the corresponding position
opposite to the said hook-bills 20, 22 for receiving said
positioning legs 344, 364. Similarly, in order to position said
self-locking member 4 on S-shaped body 2, two openings 200, 202 are
also arranged for the positioning legs of the self-locking member
4. In order to firmly fix the positioning legs 344, 364 into the
openings 220, 222, the positioning legs 344, 364 can be riveted
into the openings 220, 222 longitudinally. Said openings 220, 222
are arranged in one row longitudinally. Unlike the first
embodiment, here notches 204, 224 are arranged on the inside of
said hook-bills 20, 22 for receiving said connection portions 32',

move outwards and by this way, the connection portion 32' is locked
into the notch 204.
[0029] Now, the hook is closed and locked. One can use the thumb to
slightly push the self-locking members, which causes said arcing
portions 32', 42' to separate from the hook-bills 20, 22, and
finally the hook is opened. A force which pushes the connection
portions 32', 42' to move outwards is formed when self-locking
member is mounted on the S-shaped body, so that the self-locking
can be realized.
[0030] While the invention has been explained by reference to
certain preferred embodiments thereof, it is to be understood that
the invention is not limited to the particular details of these
embodiments, and various modifications and substitutions of
equivalents may be made thereto without departing from the scope of
