PURPOSE: To improve rupture strength by engaging a radial finger with the cutout of a sleeve in geometrical connection. CONSTITUTION: A slider 29 has a finger 28 integrally formed. The radial length of the finger 28 does not exceed twice the wall thickness of a guide tube 1. In this way, the slider 29 can be so mounted that the finger 28 may be forced into a cutout 27 before the guide tube 1 is introduced in a sleeve 8. Then, the slider 29 is centered in a hole 16 at the same time to introduce the guide tube 1 with an axial slit open upward into the sleeve 8 from downward. In such a state, the slider is guided to the axial direction in the guide tube 1, the finger 28 of the slider 29 is forced through the slit 34 in the guide tube 1 into the cutout 27 of the sleeve 8 in geometrical connection and the sleeve 8 is slid and fitted into the guide tube to be encircled with no play. |
