Connection fitting with clamping collet for elongated bodies

Abstract

A connection fitting for the fastening of elongated bodies, for example of cables ( ) or also hoses, tubes, corrugated hoses and the like, in an opening ( ), which can be a through hole or a boring in a wall ( ) of a building. The connection fitting includes a clamping collet ( ) which, in its operation position, penetrates the opening ( ) and is self expanding behind the opening ( ), and which, by means of an axial retraction opposite to the direction of insertion, is also radially compressible and thus exerts a clamping force on the elongated body. To effect this motion of retraction, a sheath ( ) is provided, which is frictionally connected or force-fit connected with a locking ring ( ), which, by rotational movement of the sheath ( ) itself turns accordingly and, by its own threading, is axially displaced until the ring ( ) abuts the wall ( ) on the opening rim ( ) and remains there in a stop position. In this way, the respective thickness of the wall ( ) is accommodated. A further turning of the sheath ( ) using the frictional coupling with the locking ring ( ) is possible, so that the clamping collet ( ), following the attainment of the stop position of the locking ring ( ), can being tensioning or be further tensioned because of corresponding axial dimensioning of the threading. For the user, it is principally necessary, to turn the sheath ( ) in a uniform direction, in order to activate an adjustment of the connection fitting to the thickness of the wall and to firmly secure the elongated body ( ) with the clamping collet.
