 lace sections 201, 202, and a clamp member 3. The first lace section 201 is strung on a shoe body 41 so as to form a criss-cross pattern on eyelet tabs 5 of the shoe body 41. The second lace section 202 is formed as a simple loop, and has lower ends 2021 connected to the first lace section 201, thereby anchoring the lower ends 2021 on the eyelet tabs 5, respectively. The clamp member 3, as shown in FIG. 2, includes an elongate casing 301, a clamping block 302, and a spring member 303. The elongate casing 301 is formed with a lateral open end 3010 for receiving the clamping block 302, a closed end 3011 opposite to the open end 3010, and a vertically extending hole unit 301xe2x80x2 for extension of the lower ends 2021 of the second lace section 202 therethrough. The clamping block 302 is slidably received in the open end 3010 of the casing 301, and is formed with a vertically extending slot unit 3021 that corresponds to the hole unit 301xe2x80x2 of the casing 301 for extension of the lower ends 2021 of the second lace section 202 therethrough. The spring member 303 is disposed in the casing 301, and has opposite ends that abut respectively against the clamping block 302 and the closed end 3011 of the casing 301. As such, the clamping block 302 is biased by the spring member 303 so as to misalign the slot unit 3021 from the hole unit 301xe2x80x2 in order to clamp the second lace section 202 between the clamping block 302 and the casing 301.
To tighten the shoe 4, the clamp member 3 is forced to move downwardly along the second lace section 202, thereby bringing the lower ends 2021 of the second lace section 202 closer together.
To loosen the shoe 4, the clamping block 302 is operated to align the slot unit 3021 with the hole unit 301xe2x80x2 against action of the spring member 303, and the clamp member 3 is then moved upwardly along the second lace section 202, thus permitting the lower ends 2021 of the second lace section 202 to move away from each.
Although the aforesaid shoe lace device 1 is easy to use, the simple loop configuration of the second lace section 202 has an unattractive appearance.
Therefore, the main object of the present invention is to provide a double-bow shoe lace device for a shoe.

lace sections 201, 202, and a clamp member 3. The first lace section 201 is string on a horseshoe body 41 so as to form a criss - cross practice on eyelet tabs 5 of the brake shoe consistency 41. The second lace section 202 is formed as a simple loop, and has low ends 2021 connected to the first lace section 201, thereby anchoring the lower end 2021 on the eyelet tabs 5, respectively. The clamp member 3, as shown in FIG. 2, admit an elongate casing 301, a clamping block 302, and a spring extremity 303. The elongate casing 301 is formed with a lateral open end 3010 for receiving the clamp block 302, a closed end 3011 opposite to the open end 3010, and a vertically extending hole unit 301xe2x80x2 for extension of the lower ends 2021 of the second lace section 202 therethrough. The clamping block 302 is slidably received in the open goal 3010 of the casing 301, and is formed with a vertically unfold time slot unit 3021 that corresponds to the hole unit 301xe2x80x2 of the casing 301 for extension of the lower ends 2021 of the second lace incision 202 therethrough. The spring member 303 is disposed in the casing 301, and has opposite end that abut respectively against the clamping block 302 and the closed end 3011 of the shell 301. As such, the clamping auction block 302 is bias by the spring member 303 so as to misalign the slot unit 3021 from the fix unit 301xe2x80x2 in order to clamp the second lace section 202 between the clamp block 302 and the casing 301. 
 To tighten the shoe 4, the clamp penis 3 is forced to motivate downwardly along the second lace section 202, thereby fetch the lower end 2021 of the second lace section 202 nearer together. 
 To loosen the horseshoe 4, the clamping block 302 is manoeuver to align the slot whole 3021 with the hole unit 301xe2x80x2 against action of the spring member 303, and the clamp member 3 is then moved upwardly along the second lace section 202, therefore permitting the lower end 2021 of the second lace section 202 to move away from each. 
 Although the aforesaid shoe lace device 1 is easy to use, the simple closed circuit configuration of the second lace section 202 has an unattractive appearance. 
 Therefore, the main object of the present invention is to supply a bivalent - bow shoe lace device for a shoe.
