Abstract: A rapid fixing device for a tubular element, in particular for the housing (1) of an optical fiber terminal block. The tubular element penetrates into the housing (1) along an inlet duct (9A3, 9A4, 9A5) in which it is fixed by a moving member (2) having a clamping slot, the moving member being movable in translation along a guide (10A1) which intersects the inlet duct. The device includes an arrangement for displacing the moving member under the effect of partial axial rotation of the blade of a tool (19) of the screwdriver type. Two operating ducts, one in the housing and the other in the moving member co-operate to convert the rotary movement of the tool into translation movement of the moving member.

Abstract: A connector for optical fibers, the connector comprising two complementary portions (1A, 1B) each including at least one semi-tubular extension suitable for forming a split tube with the corresponding semi-tubular extension on the other complementary portion with which it is assembled. Said tube carries an external locking ring (3) which surrounds the tube and which, when suitably positioned, serves to urge the semitubular extensions towards each other, thereby enabling at least one optical fiber inserted into the tube to be clamped in place.

Abstract: A junction block for end-to-end interconnection of two optical fibers, said block comprising two identical parts (1) assembled face-to-face and forming a block having a fiber-receiving duct (13) passing therethrough, said duct being built up from two half ducts each running along a corresponding one of said parts, said duct being suitable for receiving two fibers inserted into respective ends thereof, and for positioning the cores of said two fibers in end-to-end alignment inside a mid guide portion thereof (13E), and for holding said fibers in place by clamping their respective coatings inside two retaining members (13B1, 13B2) of the duct which are located adjacent to respective ends thereof and each of which is constituted by two half-members which are resiliently separable to enable a fiber to be connected to pass therethrough in order to properly position the core of said fiber for interconnection with the core of the other fiber.
