ABSTRACT:
A snap-in attachment of a headband or other support means for a hearing-protection cup is described. The snap-in contact comprises a sliding pin (6) the journal section (7) of which is oval or elliptical in cross section, and a jaw element with two resiliently deformable jaws (11, 12). The inner walls (21, 22) of the jaws (11, 12) and the wall section (20) connecting them define a locking space (13). The journal section (7) of the sliding pin can be inserted into the locking space (13) against a resilient counter member only in the direction of the longitudinal axis of the journal section (7) and is thus lockable between the jaws (11, 12) in a first locked position. After being turned (angle .alpha.) against another resilient counter member, the sliding pin is locked by its journal section (7) in the locking space (13) in a second locked position, in which it is pivotable to a limited extent (sector with angle .beta.).
