For absorbing tensile forces the end of the cast-in dowels has radial widenings, for example conical widenings a piece of pipe designed as a pouring dowel.

Nach der US3163266 wird als Schnellverbinder zur einhändigen Montage zweier senkrecht zueinander orientierter, jeweils durchgängiger Leichtprofile ein federnder Drahtbügel verwendet, welcher mittig eine Primärwendebiegung von 150° aufweist und deren Schenkel jeweils eine dazu senkrechte Sekundärwendebiegung von 180° aufweisen. Die Sekundärwendebiegung dient jeweils als formschlüssig hintergreifender Haken für ein Leichtprofil, die in der Höhe des Leichtprofils um 90° abgewinkelten Schenkel sind zusammen mit einer leicht gekröpften Primärwendebiegung als einklipbarer Haken ausgebildet, welcher die Breite des Leichtprofils hintergreift.According to US3163266 is used as a quick connector for one-handed installation of two vertically a resilient wire bracket that is oriented towards each other and consistently of light profiles used, which has a primary turning bend of 150 ° in the middle and its legs each have a secondary turn of 180 ° perpendicular to it. The Secondary turning bends serve as a form-fitting hook for one Light profile, which are angled at 90 ° in the height of the light profile together with a slightly cranked primary turning bend as a clip-on hook trained, which engages behind the width of the light profile.

Nach der US4388791 wird als Schnellverbinder zur einhändigen Montage zweier senkrecht zueinander orientierter, jeweils durchgängiger Armierungseisen ein federnder Drahtbügel verwendet, welcher mittig eine Primärwendebiegung von 180° aufweist und deren parallel verlaufende Schenkel jeweils eine dazu senkrechte Sekundärwendebiegung von 120° aufweisen, die über das Armierungseisen einklipbar ist und dieses senkrecht an dem anderen Armierungseisen kraftformschlüssig fixiert. Eine endseitige Fixierung ist damit nur bedingt möglich.According to US4388791 is a quick connector for one-handed installation of two vertically a resilient wire bracket that is oriented towards each other and in each case continuous reinforcing iron used, which has a primary turning bend of 180 ° in the middle and its parallel running legs each have a secondary turning bend of 120 ° perpendicular thereto have, which can be clipped over the reinforcing iron and this perpendicular to the other reinforcing bars fixed with a positive fit.
