Date Dec. 8, 1983.The apparatus comprises at least three parallel rods (1, 2, 3) adapted to form between themselves a channel (4) for accommodating the ends of the two fibres, and means for keeping the rods together and clamping the fibre ends in the channel between the rods. In accordance with the invention, each rod (1, 2, 3) has two plane surfaces (7, 12; 8, 9; 10, 11) intersecting along a longitudinal edge. One of these plane surfaces on the respective rods bears against one of these plane surfaces on an adjacent rod such that said longitudinal edges of the rods extend parallel to, and are distributed round a longitudinal axis of symmetry (6). The rods are further mutually displaceable relative to the axis of symmetry (6) by sliding between the plane surfaces bearing against each other to form the channel (4) for accommodating the fibre ends.
