    [0015] The at least one engaging arm 36 is arranged at the base portion 34, and the at least one engaging arm 36 is substantially transversely arranged with respect to the first wall 20a. In the embodiment, the at least one engaging arm 36 is arranged at a second side (such as a front side) opposite to the first side of the base portion 34, which is only exemplary. The at least one engaging arm 36 is resiliently movable around a hypothetical axis X. The hypothetical axis X is substantially parallel to the first wall 20a which is longitudinally arranged.
    [0016] Preferably, the at least one engaging arm 36 can be three pairs of engaging arms, which is only exemplary and the number of the engaging arm 36 is not limited thereto. Each pair of the engaging arms 36 includes a first engaging arm 36a and a second engaging arm 36b. The structures of the first engaging arm 36a and the second engaging arm 36b are substantially identical. The first engaging arm 36a and the second engaging arm 36b are separated from each other by a distance G. The distance G is less than the width W. Furthermore, each of the first engaging arm 36a and the second engaging arm 36b is arranged with an engaging portion. For example, the first engaging arm 36a is arranged with a first engaging portion 46a, and the second engaging arm 36b is arranged with a second engaging portion 46b. Preferably, the structures of the first engaging portion 46a and the second engaging portion 46b are configured to be symmetrical. Each of the first engaging portion 46a and the second engaging portion 46b includes a guiding segment 49. The guiding segment 49 can be arranged as an inclined surface or a curved surface. Furthermore, the first engaging portion 46a can be a hook facing upwardly, and the second engaging portion 46b can be a hook facing downwardly (shown in FIG. 5). However, the directions of the first engaging portion 46a and the second engaging portion 46b are not limited thereto.
    [0017] Preferably, the base portion 34 includes a surface 45 and a space 47 adjacent to the surface 45. The surface 45 is substantially a plane. The space 47 is formed at the base 34, and an opening of the space 47 is located at the surface 45. The at least one engaging arm 36 is arranged inside the space 47, and a length of the at least one engaging arm 36 does not exceed the surface 45. Furthermore, the auxiliary portion 38 is substantially perpendicularly connected to the base portion 34, and the auxiliary portion 38 exceeds the surface 45 of the base portion 34 by a predetermined distance. The auxiliary portion 38 includes at least one fastening feature 38a to be inserted by a fastening member.
    [0018] As shown in FIG. 5, the second wall 20b of the furniture piece 20 is mountable to the at least one engaging arm 36 along a mounting direction Y via the at least one mounting portion 30. The mounting direction Y is substantially perpendicular to the hypothetical axis X, and the mounting direction Y is substantially parallel to the at least one engaging arm 36 which is transversely arranged.
    [0019] As shown in FIG. 6 and FIG. 7, when the second wall 20b of the furniture piece 20 is moved along the mounting direction Y to a predetermined distance and is close to the first wall 20a, the mounting end 48 of the at least one mounting portion 30 contacts the guiding segments 49 of the first engaging portion 46a and the second engaging portion 46b of the at least one engaging arm 36, wherein a distance between the two mounting ends 48 defines the width W.
    [0020] As shown in FIG. 8 and FIG. 9, when the second wall 20b of the furniture piece 20 is continued to be moved along the mounting direction Y, the mounting end 48 of the at least one mounting portion 30 pushes against the guiding segments 49 of the first engaging portion 46a and the second engaging portion 46b of the at least one engaging arm 36 to drive the first engaging arm 36a and the second engaging arm 36b to move resiliently around the hypothetical axis X, such that the first engaging arm 36a and the second engaging arm 36b are approached toward each other. Meanwhile, the first engaging arm 36a and the second engaging arm 36b are in a state of accumulating a resilient force, and the end portions of the first engaging arm 36a and the second engaging arm 36b move slightly into the accommodating space 31.
    [0021] As shown in FIG. 10 and FIG.11, when the second wall 20b of the furniture piece 20 is further moved along the mounting direction Y, the mounting end 48 of the at least one mounting portion 30 further passes the first engaging portion 46a and the second engaging portion 46b of the at least one the engaging arm 36, such that the first engaging portion 46a and the second engaging portion 46b of the at least one engaging arm 36 are accommodated in the accommodating space 31. Once the mounting end 48 of the at least one mounting portion 30 passes the first engaging portion 46a and the second engaging portion 46b, the first engaging arm 36a and the second engaging arm 36b release the resilient force, such that the first engaging arm 36a and the second engaging arm 36b return to the state that the first engaging arm 36a and the second engaging arm 36b are spaced by the distance G. As such, the first engaging portion 46a and the second engaging portion 46b engage with the mounting end 48 of the at least one mounting portion 30 and abut against a wall surface of the mounting end 48 of the at least one mounting portion 30. Therefore, the second wall 20b can be fixedly connected to the first wall 20a via the connecting device 32 in a tool-free manner.
    [0022] Moreover, the at least one mounting portion 30 of the connecting device 32 can be detachably disengaged from the first engaging portion 46a and the second engaging portion 46b. For example, when a user applies a force to deform the first engaging arm 36a and the second engaging arm 36b (as the state shown in FIG. 9), the first engaging portion 46a and the second engaging portion 46b are no longer engaged with the mounting end 48 of the at least one mounting portion 30, such that the second wall 20b can be detached from the first wall 20a along a detaching direction opposite to the mounting direction Y.
    [0023] As shown in FIG. 12 and FIG.13, the connecting device 32 can further include a guiding portion 50, and the guiding portion 50 can be a curved surface or an inclined surface. When the second wall 20b of the furniture piece 20 has a mounting error B with respect to the first wall 20a, the second wall 20b of the furniture piece 20 can be guided and corrected by the guiding portion 50 (as shown in FIG. 14), which can facilitate the at least one mounting portion 30 to be mounted to the engaging portion (such as the first engaging portion 46a and the second engaging portion 46b) of the engaging arm 36 (as shown in FIG. 11).
    [0024] For example, during the second wall 20b of the furniture piece 20 being moved toward the first wall 20a along the mounting direction Y, if the second wall 20b of the furniture piece 20 has the mounting error B with respect to the first wall 20a (as shown in FIG. 12), with the mounting end 48 of the mounting portion 30 contacting the guiding portion 50 (as shown in FIG. 13), the second wall 20b of the furniture piece 20 can be guided and corrected (as shown in FIG. 14). As such, the mounting end 48 of the at least one mounting portion 30 can be successfully engaged to the first engaging portion 46a and the second engaging portion 46b (as shown in FIG. 11).
    [0025] As shown in FIG. 15, FIG. 16 and FIG.17, when the second wall 20b of the furniture piece 20 is detached from the first engaging portion 46a and the second engaging portion 46b via the mounting portion 30, another type of plate (such as a wood plate or other solid plate) can be used to replace the second wall 20b. For example, an end 202 of the another second wall 200 used in the furniture piece 20 is capable of abutting against the surface 45 of the base portion 34 of the connecting device 32, at least one fastening feature 38a is provided to be inserted by the at least one fastening member 52 and the fastening member 52 is fastened to at least one corresponding fastening feature 204 of the another second wall 200, such that the another second wall 200 is fixed to the auxiliary portion 38, and the another second wall 200 can be connected to the first wall 20a thereby.
    [0026] Therefore, the connecting device 32 is capable of connecting two types of second walls (for example, the aforesaid second wall 20b and the another second wall 200) with different structures to the first wall 20a without using other accessories, which can satisfy different market demands.
    [0027] To sum up, the connecting device 32 according to the embodiment of the present invention includes features as follows.
    [0028] First, the second wall 20b of the furniture piece 20 can be connected to the first wall 20a in a tool-free manner, which facilitates and eases the assembling and detachment.
    [0029] Second, the at least one engaging arm 36 is substantially transversely arranged with respect to the first wall 20a which is longitudinally arranged, and the mounting direction Y of the second wall 20b is substantially parallel to the engaging arm 36 which is substantially transversely arranged. As such, it facilitates a user to connect the second wall 20b to the first wall 20a.
    [0030] Third, the connecting device 32 is capable of connecting two types of second walls (20b and 200, shown in FIG. 3 and FIG .15) with different structures to the first wall 20a without using other accessories, which can satisfy different market demands.
