bent back on itself to form a bight portion 22 and a
base leg 24 and an engaging leg 26. The base leg 24 is 50 opening, said bar bent back on itself to form a base leg,
a bight portion, a fastening means adapted to engage a
longer than the engaging leg 26 and in spaced relation

base leg 24 and engaging leg 26. The said apex 30 of 55 bar to said frame.
the tab 28 points toward the plane of the bight 22. A
stud 32 may be formed from the base leg 24 protruding
toward the plane of the engaging leg 26.
The tab 28 could be a protuberance or the free end
of the engaging leg 26 formed to hook behind the frame 60
as disclosed in FIGS. 8 and 9.
To engage the buckle 10 with a strap 12, the strap
12 is laid across the gripping legs 14 in contact with the
protuberances 38, as illustrated in FIGS. 1, 4, 6, and 7.
The strap 12 in the area formed by the frame is pushed 65
down between the gripping legs 14 to form a loop be
yond the plane of the frame 11. The bar 18 is then
engaged to the frame 11 by placing the said base leg
