Aluminium tube connectors – the versatile solution for industrial use

With their simple clamping principle, the aluminium tube connectors enable fast assembly of both round and square precision tubes. The wide range of versions makes this system an attractive and cost-effective alternative to conventional welded connections.

The simple assembly technology of the tube connectors eliminates the need for time-consuming and costly drilling and welding work. At the same time, RK tube connectors create durable, high-strength connections, whilst also being easy to detach. So these tube connections allow you to tailor handling or automation configurations to suit the specific requirement, and modify them at any time.

  • Aluminium tube connectors – product benefits at a glance:
  • Aluminium connectors for medium to high torsional stress
  • Quick availability minimises stockholding
  • No special tools required for installation and assembly
  • Simple clamping principle as a cost-effective alternative to welded connections
  • Thanks to the large range of clampable pipe cross sections, in round and square versions, this system makes for considerable construction freedom

Our application expertise and decades of experience as a manufacturer of clamp connectors mean that you can have complete confidence in RK tube connection systems.

Block form tube connector

quad® tube connector

The complete tube connection system. The huge range of models, clamp diameters and possible combinations is unique on the market. The straight external contours distinguish the block form range from the industrial design range in terms of appearance. The multi-piece versions enable the clamp connectors to be integrated into existing constructions retrospectively. Made from extruded aluminium profiles, the cuboidal, anodised connecting elements have a timeless appearance and can withstand exceptionally high loads.

Material tube connector: cast aluminium

  • Wide variety of different diameters and connector designs
  • Single-piece clamp connectors (the clamp connectors are pushed onto the tube)
  • Comprehensive range of accessories

Material tube connector: cast aluminium

  • Higher torque
  • Even external contours
  • Multi-piece clamp connectors (the clamp connector is fitted around the tube and then fastened)

Material tube connector: extruded aluminium profile

  • Maximum torque
  • High-quality anodised finish with straight external contours
  • Stainless steel cylinder head screws (usually countersunk)
  • Single-piece and multi-piece clamp connectors

Aluminium tube connectors in different versions

The tube connection system comprises clamp connectors for static and dynamic loads. They are very easy to join together to form functional components for use in any industry. You can choose between single-piece tube connectors for quick and inexpensive installation, or multi-piece tube connectors that are also suitable for retrofitting and extensions.

  • Single-piece clamp connector:
  • for quick, cost-effective installation
  • for connecting round tubes
  • Multi-piece clamp connector:
  • suitable for retrofitting and extensions
  • for connecting round and/or square tubes

In addition to different versions of aluminium tube connectors, you can also buy plastic tube connectors and stainless steel tube connectors at RK Rose+Krieger. Our range also includes special adapter sleeves for your aluminium tube connectors. The 28 adapter sleeve reduces the 30 mm internal diameter of the aluminium clamp to the standard 28 mm tube size. This allows two systems to be directly connected, giving the user greater freedom for system design. Order now!

NEW: Tube connectors with ball joint in size 18

RK Rose+Krieger is expanding its product range of aluminium (Solid Clamps) and plastic (Light Clamps) tube connectors to include a total of seven clamping elements with a size 18 ball joint.

All the new ball clamps have a universal connecting plate that can be rotated 360° to ensure flexible connection and feature two slotted holes and two threads. The connecting plates’ pivoting range is 60° in each case. The clamping elements can be freely adjusted and easily fixed. This makes them ideal for the construction of flexible tube structures, as well as for mounting sensors, reflectors and other elements that need to be precisely aligned or readjusted more frequently, depending on the production requirements and product. A special surface coating on the ball joint makes for a high-strength clamping connection.


  • can be pivoted freely by 60°/can be rotated 360°
  • can be combined with size 18 and 30 tube connectors
  • the clamps feature a universal connecting plate for flexible integration
  • high-strength clamping thanks to special finishes
