Spannzangenvorrichtung

摘要

The invention relates to a collet device, in particular for snap closure attachments for gaseous and/or liquid media which comprises a clamping plunger (4) and a plurality of collets (3) each with a connection end (3a) and a bearing end (3b). The bearing ends (3b) of the collets (3) are detachably suspended on the clamping plunger (4) and said collets can be displaced axially with the clamping plunger (4) using an actuating member. For simple and rapid replacement and assembly of the collets the invention proposes that the collet arrangement (3, 4) is linked to a fixing member (5; 5') movable in relation to the collet arrangement (3, 4) in order to lock the bearing ends (3b) positively.
