A side wall of the guide cylinder (4) is provided with an axially elongated guide groove (5) through which the engagement projection (3) is passed, and an annular locking recess (10) is formed around the portion of an outer surface of the guide cylinder (4) which is below a lower end of the guide groove (5). This guide cylinder (4) is inserted in a sleeve (11) so that the guide cylinder (4) can be turned. The sleeve (11) is provided at its lower portion with a locking rib (20) engageable with the locking recess (10), whereby the sleeve (11) is combined with the guide cylinder (4) so that the sleeve (11) does not come off from the guide cylinder (4), the sleeve (11) being provided in its inner surface with a helical knurled thread (13) having innumerable projections and recesses.
