A device for holding a perforated object, for instance a perforated card or a key ring. The device includes a first holder unit for coaction with the perforated object, a second holder unit for coaction with a piece of clothing on the person carrying the object, and a reel or winder that acts between the two units. The reel includes a tongue-shaped protrusion from which the line can be fed out from and into the reel. The first holder unit includes a closable hasp which is intended for coaction with the hole in the perforated object. The second holder unit coacts with the reel or winder via a hooked part which is attached to an eyelet on the reel. Coaction between the second holder unit and said clothing is effected with the aid of a clamping device belonging to the second holder unit. The first holder unit includes first and second wing-like protrusions on opposite sides of the holder unit relative to the hasp. These wing-shaped protrusions are adapted so that the tongue-shaped protrusion can be embraced by the two wing-shaped protrusions when the line has been reeled-in, whereby the first holder unit is prevented from twisting or rotating about the axis of the line that extends between the reel and the first holder unit when the line has been taken-up by the reel. |
