Abstract: Detachable links are formed by a first link having a part-spherical end joined to a cylindrical first intermediate portion and a second link having a receiving end with spaced, generally U-shaped arms defining a slot. The arms resiliently spread apart to receive and then snap back to capture the part-spherical portion, leaving the cylindrical portion in the slot. The joined links may be freely relatively pivoted through substantially 180 degrees and may be freely relatively rotated through a full 360 degrees about the axis of the cylindrical portion. The part-spherical portion may have one upstanding cylindrical stub or a diametrically opposed pair which are positionable either between the legs of the arms or in the slot between arms. These stubs limit the free rotation between links by resisting same except as permitted by forcible rotation in 90 degree steps due to spreading apart and snapping back of the arms.

Abstract: Method and installation for the separate conditioning of matches (1) in a package subdivided in oblong compartments (4) wherein a match (1) is arranged in each of them, the compartments (4) being closed at one end and open at the opposite end so that the head (11) of a match is located at the closed end and the opposite portion of the match goes beyond the open end of the compartments (4) to allow for the removal of the match from its compartment. The matches (1) are first arranged in a relatively flat prismatic core (2) comprising oblong housings (4) for the matches, those housings being arranged one after the other and separate in their longitudinal direction by partitioning walls (3), the housings (4) being almost completely open along at least one of their longitudinal open sides (5), the sides (5) being then covered by a closure element (6) so that oblong compartments (4) are formed wherein the matches (1) are removably squeezed.
