Abstract: A device for fixing an end of a shouldered casing containing and guiding a ulling or pressing cable includes a holding block with a recess extending axially into the block and a slot extending axially through and radially into the block and into the recess for inserting the casing into the block and recess. An edge surface of the recess surrounds and interferringly engages a shoulder of the casing and while a bottom of the recess interferringly engages the shoulder. A flexible tongue is provided facing the recess and serving as a stop for either the transverse end surface of the end of the casing or a similar transverse side surface of the shoulder.
