Abstract: The support is constituted by a spool comprising a base (F), and outer wall (1) having openings (4) therethrough, an inner wall (2) having openings (5) therethrough, and at least one cylinder (3). An outer ring (A) between the inner and outer walls serves to store slack lengths of fiber-carrier, and an inner ring (B) between said inner wall and said cylinder(s) serves to store slack lengths of optical fiber together with connection devices (11) for interconnecting the fibers. Lugs are provided on the inner and outer walls and on the cylinder(s) in order to hold the fiber-carriers and the fibers in place while the supports are being manipulated. The cylinders may be provided with rotatable covers, in which case the cylinder lugs are fixed to the covers.

Abstract: Crimping tongs in particular for crimping a sleeve on a cable, said tongs having jaws coupled to each other so that one moves relatively to the other, a cam (15) driven by a ratchet wheel (16) which actuates a toggle joint device (20,21,22) a catch being installed on the moving handle (13) so as to drive the ratchet wheel step by step by moving the moving handle, the toggle joint device making the moving jaw (12) rotate in the closing direction. With a view to axial crimping, the moving jaw (12) has a moving die (14) which moves rectilinearly. A spring (25) biases the toggle joint to move the one jaw toward the other, and a trigger (19) is pressed to open the jaws sufficiently for insertion of a sleeve to be crimped. Releasing the trigger causes the jaws to hold the sleeve under the action of spring (25); so that the crimping action can be performed with one hand.
