Abstract: A retainer (A) for a card, especially ID-card, having a bottom plate (1) and thereto applied or formed opposite edges (2, 3), which are formed with slots (2a, 3a) and the bottom parts (2a', 3a') of which are intended to guide opposite edge portions (4, 5) of the card when the card is moved into said retainer. Between said edges (2,3) one or more means (6,7) are arranged to give the card a curvature between the edges. Said means (6,7) is in the form of two parallel ridges formed in the bottom plate (1) and said ridges (6,7) are omitted at certain portions (8,9). Said portion (8,9) is adjacent but at a distance from stop means (10,10a11,11a) in the retainer for the movement of the card (B). Said stop means (10,11) for the card is in the form of a rim having a central notch or recess (10a) and between the stop means and the portion are, in the direction of movement for the card, arranged wedge formed ridges (6a,7a).

Abstract: A holding arrangement intended to hold a plate-like element to a post. The holding arrangement is provided with a peg having different cross-sections formed at two perpendicular coordinates. In a first position of rotation of the arrangement relative to the first element, the peg can be inserted into the element, and upon further rotation of the arrangement to a second position of rotation, a larger cross-section of the peg clamps the holding arrangement firmly against surfaces formed in the first element.

Abstract: A device for attaching a second component (handrail) to a first component (upright) in a secure but detachable manner. The second component has a clip in the form of an angle. The first component has a recess large enough to accept the clip. The first component works in conjunction with a locking device so designed that in one position it will accept the clip but that in a different position it will permit the locking of the clip.

Abstract: Device for clamping two parallel directed means, comprising two mutually cooperating parts. One part having one or more grooves, each groove intended to surround partially a means intended for said groove. The second part is turnable attached to said first part in order to expose the grooves and cause the means to cooperation in a first position and to clamp the means in a second position. Said second part is formed with plane surfaces intended, by turning from said first to said second position, to slide along the means and press the means into the grooves.
