A string collecting device and an article having a string are provided, wherein the string collecting device includes a rotating part (1) and a string winding part (2) configured to wind a string; the rotating part (1) is provided with at least one movable part (3) that is capable of moving; the movable part (3) is configured to be engaged with the string winding part (2) when the rotating part (1) is rotated towards a string collecting direction, and wherein when the at least one movable part (3) is engaged with the string winding part (2), the three, namely, the rotating part (1), the at least one movable part (3) and the string winding part (2), are connected in synchronous rotation. This string collecting device is simple in structure and easy in operation, wherein when a user needs to tighten the string, the operation can be completed just by rotating the rotating part with a single hand towards the string collecting direction.

To provide a fastening tool that can solve problems that are raised upon locking the opening portion of clothing, baggage or the like, and can also positively lock the portion to be locked at a desired position without the necessity of any processing jobs, such as caulking, sewing and the like, so as to be freely detachably locked. The fastening tool is provided with at least a pair of fastening members a and b which have detachably attaching portions that are freely detachably attached to each other, and each of the fastening members a and b has a substrate with a piercing needle formed on one of the surfaces, a bottom plate that is penetrated by the piercing needle, a pierce catch made of a cap-shaped member to cover the tip of the penetrated piercing needle, and detachably attaching portions that are freely detachably engaged with each other.

A closure device (1) for releasably connecting two parts with each other comprises a first closure member (2) having a rigid first locking protrusion (210) and a second closure member (3) which is attachable to the first closure member (2) and in a closed position is held on the first closure member (2). The second closure member (3) has a rigid second locking protrusion (304), wherein the second locking protrusion (304) can be brought into engagement with the first locking protrusion (210) in an engagement direction (E) and in the closed position engages the first locking protrusion (210) in a positive locking manner. The first closure member (2) comprises a first magnetic member (23, 23A, 23B) and the second closure member (3) comprises a second magnetic member (33, 33A, 33B), the first magnetic member (23, 23A, 23B) and the second magnetic member (33, 33A, 33B) being constituted to magnetically attract each other when the second closure member (3) is attached to the first closure member (2) for closing the closure device (1). Furthermore, the first closure member (2) comprises a blocking element (24, 24A, 24B), wherein the blocking element (24, 24A, 24B) in the closed position faces a back face (308) of the second closure member (3) facing in a direction opposite to the engagement direction (E), the blocking element (24, 24A, 24B) being constituted to prevent the second locking protrusion (304) to move out of its engagement with the first locking protrusion (210) in the direction opposite the engagement direction (E) when the closure device (1) is in its closed position. By these means a closure device is provided which can easily and comfortably be handled and at the same time is suitable to take on large loads.
