As shown in Figs. 1 to 3, a rubber locking device according to the invention is composed of a rubber strip 1, a clamp board 2, two hook bases 4, four fastener boards, four screws 5, a soft spacer 6, a U fastener base 9 and a rubber ring 10.

The rubber strip 1 is in form of a long board provided with a central hole 11, two positioning crevices at two sides of the central hole 11, pluralities of locking holes 13 arranged on the rubber strip 1, a pull 14 and anti-slip roughness 15 at each of the extending rear ends of the rubber strip 1.

The clamp board 2 is provided at the bottom with a central post, which is provided with positioning blocks 22 at two sides and a central screw hole 23 inside. Referring to Figs. 2 and 3, when assembling the rubber strip 1 onto the top of the bicycle seat bag 7, it is required that the seat bat 7 is provided with a through hole 71 and two slots 72, such that the central post 21 on the clamp board 2 goes through the central hole 11 of the rubber strip 1 and then the through hole 71 on the seat bag 7, while the positioning blocks 22 go through the positioning crevices 12 of the rubber strip 1 and then the slots 72 on the seat bag 7. By way of mounting a fastener board onto the central post 21 and fasten the screw S from the interior of the seat bag 7 through the screw hole 42 to the central screw hole 23, the rubber strip 1 can be firmly fastened to the seat bag 7. As the protruding positioning blocks 22 can be engaged into the positioning crevices 12 and then the slots on the bag 7, the clamp board 2 and rubber strip 1 would not rotate to deflect from each other.

Each of the hook bases 3 is provided with two protruding positioning posts 31 at one end, a hook at the other end, and a screw hole 32 between the two positioning posts 31. Further refer to Figs. 2 and 3, to firmly fasten the hook bases 3 to the two sides of seat bag 7, the seat bag 7 need be provided with three holes at each side, such that the positioning posts 31 at the hook bases 3 will go through the holes 73 on the sides of the seat bag 7 and the fastener boards 4 will be mounted onto the positioning posts 31 via the positioning holes 41. A screw 5 is screwed from the interior of the seat bag 7 through the screw hole 41 to the screw holes 32 for fastening purpose.

The U locking base 9 is provided with two protruding positioning posts 91 at one end, a screw hole 92 between the two positioning posts 91, a U frame 93, which has a locking hook 94 at one end and two adjusting hooks 95 at the other end, corresponding to the positioning posts 92, and a soft spacer 6 for cushioning inside of the U frame 93. A rubber ring 10 having a pull 14 and anti-slip roughness 15 at one end is hooked with the locking hook 94.

As shown, when assembling the U fastening base 9 to the front end of the seat bag 7, which is also provided with three holes 73, the two positioning posts 91 on the U fastening base 9 go through the holes 73 on the seat bag 7.
