According to a preferred embodiment of the present invention, a clip 10 for a construction machine used to fix a connector to a structure in a vehicle for a construction machine includes a connector body 11 having an engagement hole 11a formed thereon to be engaged with the structure, a connection plate 12 formed to extend from the connector body 11, a pair of guides 13 formed to extend from one side surface and the other side surface of the connection plate 12, respectively, a moving latch fixing portion 14 located in the center in the pair of guides 13 and extending from the one side surface and the other side surface of the connection plate 12, respectively, and a moving latch 15 provided to extend from the one side surface and the other side surface of the moving latch fixing portion 14, respectively, and having a lower surface formed to keep a predetermined distance from the connection plate 12.
As illustrated in FIG. 1, the clip 10 according to an embodiment of the present invention includes the connector body 11, the connection plate 12, the guide 13, the moving latch fixing portion 14, and the moving latch 15.
As illustrated in FIG. 2, the engagement hole 11a is formed on the connector body 11 to fix the clip 10 to the structure of the vehicle of the construction machine using a bolt or the like. The connector body 11 is formed in a predetermined shape so that the connector body 11 can be fixed to the structure of various types of vehicles.
The connection plate 12 is formed to extend from the connector body 11, and has a flat shape.
The pair of guides 13 are formed to extend from an upper surface and a lower surface of the connection plate 12, respectively, as two guides 13 as a whole.
The moving latch fixing portion 14 is formed between the pair of guides 13, and is located in the center in the length direction of the guides 13.
The moving latch 15 is formed to extend from the one surface and the other surface of the moving latch fixing portion 14 toward the end direction of the guides 13. As a result, the moving latches 15 are formed to have a line of symmetry based on the moving latch fixing portion 14.
As illustrated in FIG. 4, the lower surface of the moving latch 15 is formed to keep a predetermined distance from the connection plate 12, and thus the moving latch 15 can move within the distance range. As a result, when the connector and the clip 10 are fastened to each other, the moving latch 15 moves in an opposite direction to the connector to facilitate the fastening, and when the connector and the clip 10 are released from each other, the moving latch 15 can move to facilitate the releasing. Further, since the moving latch 15 is provided on each of the two guides 13, it is possible to fix two or more connectors for electric and electronic wires to one clip 10.
In the clip 10 according to the preferred embodiment of the present invention, the moving latch 15 includes a projection piece 15a projecting to an outside of the guides 13, an extension piece 15b formed to extend from the projection piece 15a to the moving latch fixing portion 14 and an inclined piece 15c projecting from one end of the extension piece to the end of the guide 13, and having inclination.
As illustrated in FIG. 3, four moving latches 15 are provided on the clip 10, and each of the moving latches 15 includes the projection piece 15a, the extension piece 15b, and the inclined piece 15c. 
The projection piece 15a is a portion that projects to the outside of the end of the guide 13. Since the projection piece 15a is provided, it is possible for a user to hold and move the projection piece 15a by the hand when releasing the connector. It is preferable that the end of the projection piece 15a is inclined so that the projection piece 15a can be conveniently held by the hand.
The extension piece 15b is a portion that is formed to extend from the projection piece 15a to the moving latch fixing portion 14.
The inclined piece 15c is a portion that is formed to extend from one end of the extension piece 15b to the end of the guide 13, and has an inclined surface. When the connector is fastened to or released from the clip 10, the connector slides along the inclined piece 15a. 
In the clip 10 according to the preferred embodiment of the present invention, the guide 13 includes a pair of first vertical plates 13a extending from one side of the connection plate 12, a horizontal plate 13b formed to extend from an end of the first vertical plate 13a to the outside and a second vertical plate 13c extending downward from the end of the horizontal plate 13b with a height that is lower than that of the first vertical plate 13a. 
As illustrated in FIG. 1, each of the pair of the guides 13 includes the first vertical plate 13a, the horizontal plate 13b, and the second vertical plate 13c. 
The pair of first vertical plates 13a are formed to extend from the connection plate 12.
The horizontal plate 13b is formed to extend from the end of the first vertical plate 13a to the outside.
The second vertical plate 13c is formed to extend from the end of the first vertical plate 13a, and is in parallel to the first vertical plate 13a. The overall length of the second vertical plate 13c is shorter than the length of the first vertical plate 13a. 
In the clip 10 according to the preferred embodiment of the present invention, the connector includes a pair of channels formed to slide along the guides 13; and a locking protrusion 22 located in the center in the pair of channels and formed to slide along the inclined surface of the inclined piece 15c while the connector slides and to lock in one side of the inclined piece 15c. 
The connector includes the channel and the locking protrusion 22.
A pair of channels is provided, and the locking protrusion 22 is provided in the center position in the length direction of the pair. The locking protrusion 22 is point symmetrical to the inclined piece 15c so as to be locked in one side of the inclined piece 15c. That is, since the inclined piece 15c is in the shape of a right-angled triangle, the locking protrusion 22 is also in the shape of a right-angled triangle, and their surfaces that correspond to the height of the right-angled triangles become in surface contact with each other.
As illustrated in FIG. 5, the channels are provided to be fitted into the guide 13, and the connector can slide. While the channel is fitted into the guide 13 to slide, the locking protrusion 22 slides along the upper surface of the moving latch 15, and after passing through the inclined surface of the inclined piece 15c, the locking protrusion 22 is locked in one side of the inclined piece 15c. It is preferable that the locking protrusion 22 has a locking groove so that the locking protrusion 22 becomes in contact with the one side of the inclined piece 15c, and as the locking protrusion 22 is fitted into the locking groove, the locking protrusion 22 naturally makes contact with the moving latch 15.
As illustrated in FIG. 2, according to the embodiment of the present invention, it is possible that the connectors are engaged with the lower end surface and the upper end surface of the clip 10. Further, since the engagement of the connector with the lower end surface or the upper end surface of the clip 10 is performed along the moving latch 15, the bidirectional sliding of the connector becomes possible. As a result, two connectors can be fixed to one clip 10, and when the connector is fastened to or released from the clip 10 using the moving latch 15, the connector fastening portion can be prevented from being damaged.
As illustrated in FIG. 4, in the case where the connector moves in the fastening direction 40 and is assembled with the clip 10, the moving latch 15 naturally goes down within the moving space 30 and then returns to its original state, so that the connector can be fastened without damaging the connector fastening portion.
In the case where the connector moves in the releasing direction 50 that is opposite to the fastening direction 40, the connector is not released due to the locking structure of the inclined piece 15c and the locking protrusion 22. However, in the case where the moving latch 15 is moved in the opposite direction to the connector within the range of the moving space 30 using the projection piece 15a, the connector can be released without damaging the fastening structure of the clip 10 and the connector.
