A connection fitting for the fastening of elongated bodies, for example of cables (2) or also hoses, tubes, corrugated hoses and the like, in an opening (3), which can be a through hole or a boring in a wall (4) of a building. The connection fitting includes a clamping collet (9) which, in its operation position, penetrates the opening (3) and is self expanding behind the opening (3), 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 (11) is provided, which is frictionally connected or force-fit connected with a locking ring (15), which, by rotational movement of the sheath (11) itself turns accordingly and, by its own threading, is axially displaced until the ring (15) abuts the wall (4) on the opening rim (12) and remains there in a stop position. In this way, the respective thickness of the wall (4) is accommodated. A further turning of the sheath (11) using the frictional coupling with the locking ring (15) is possible, so that the clamping collet (9), following the attainment of the stop position of the locking ring (15), 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 (11) 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 (2) with the clamping collet.
A connection fitting for fastening elongated bodies, for example cables (2), hoses, tubes, corrugated piping or the like, in an opening (3), especially a through hole or a boring in a wall (4) of a building, wherein the connection fitting (1) comprises a gripping connector (5) which extends axially in a direction of insertion and in an operational position, is adapted to be inserted forward into the opening (3), the connector (5) including holding tongues formed by circumferentially arrayed axial slots (6), a self expanding, clamping collet (9) extends axially in the direction of insertion through the connector (5), which clamping collet (9) is circumferentially compressible, by a retracting axial motion and includes an inclined surface that extends through a narrower interior of the connector (5), whereby, to effect said retracting axial motion of the clamping collet (9), an exterior sheath (11) is provided, and a stop (13) which is adapted to exert a clamping action on a rim (12) of the opening (3) proximal to the direction of insertion, characterized in that the connector (5) of the connection fitting (1) at an area adapted to be positioned behind the opening (3) in the direction of insertion includes radially, projecting holding protrusions (8) which are adapted to engage behind a rim (14) of the opening (3) and in that the stop (13) is placed upon a locking ring (15) which is axially displaceable by a threaded connection to the connector (5) of the connection fitting and that the sheath (11) which is adapted to tension the clamping collet (9), is frictionally connected with the locking ring (15), so that rotational movement of the sheath (11) for tensioning the collet (9) results in a rotation of the locking ring (15) and an approach of the stop (13) to the wall (4), and that the sheath (11) is adapted to be further rotated, even when the locking ring (15) has abutted the wall (4) of the building.
