To provide a unique connection fastener for promptly avoiding problems such as the entanglement with a leg, the disengagement of a sheet, the crack of a connecting band, and the maladaption to minor shaft fasteners 1 with the connection system and form of the fasteners 1.

Shaft portions of the plurality of fasteners 1 are fitted through upper cylindrical bodies 2 and lower cylindrical bodies 3 formed of synthetic resins, and the fasteners 1 are mutually connected via a band synthetic resin connecting sheet 4 arranged between the upper cylindrical bodies 2 and the lower cylindrical bodies 3. The connecting sheet 4 has through-holes 6a, 6b for the fasteners 1 to pass therethrough. It is formed to be hardly bent in the cross direction or to be bent in the cross direction. Thus, the connection fastener of a straight or coil type is obtained.
