A one-touch coupling unit for a toy is provided to help a child to be able to easily interconnect or assemble parts of diverse size and shape of the toy without using an instrument such as a driver or a wrench. A one-touch coupling unit is inserted into a hole(100a) formed in a part(100) of a toy. The coupling unit is constituted of a male coupling piece(10) and a female coupling piece(20), wherein the male coupling piece(10) includes a dome shaped head(11) with a recessed groove therein and a number of circular projections(12) protrudedly formed on the head at regular intervals, and the female coupling piece is constituted of a hollow body with four separating grooves(21) formed in a longitudinal direction thereof, and a pair of clamping portions(22) disposed on opposite sides to be engaged with the circular projections of the male coupling unit. |
