<p>Coupling for pivotably coupling a cradle arm (1) part to a base part (2) of a telephone. The coupling comprises at least three pivot members fitted in a row on the parts and having a common pivot axis (9), each member comprising an element fitted on one part and an element fitted on the other part. The members are of two types, the central member being of a different type from the other two members. An element of a member of a first type is a hook (10) which is radially bendable relative to the pivot axis (9) and the corresponding other element (16) has a recess (24) for receiving therein the free end of the hook after the assembly of the parts. An element of a member of a second type is a supporting element (19) for supporting thereon the corresponding other element (18) after assembly. Points of the elements touching each other after assembly all lie essentially on the pivot axis, each member having space at its contact points to allow it to turn the parts about the pivot axis between two different positions thereof, while the other element of the member of the second type is bounded by two edges intersecting one another on the pivot axis.</p> |
