Abstract

Pivotal link (1) as a connection piece between two construction parts, whereby at least one construction part is supported rotatable around its horizontal axis. The essence of the invention consists in that PA1 the pivotal link consists of a hose or a hose-like body made of elastomeric material, whereby an embedded strength carrier (4) is present between the hose core (2) and the hose cover (3), said carrier consisting of threads forming one or multiple layers and extending at an angle .alpha. amounting to zero degrees based on the axial direction of the pivotal link, or only insignificantly deviating from zero degrees with a crossed arrangement of the threads; and that PA1 the pivotal link is additionally provided with rings (7), the latter being arranged in the radial direction.
