The invention relates to a coupling for hoses for media under pressure. The coupling includes a female part and a nipple. The nipple fits into the female part. A lock ball is provided for locking the nipple in the connected position with the female part. A locking sleeve is spring-loaded toward a locking position in which it holds the ball lock in the engagement position. The locking sleeve can be moved, counter to the spring-loading, to a release position in which the ball lock is released. The movement of the locking sleeve to the release position includes both rotation about the longitudinal axis of the coupling and axial displacement parallel to this axis.

Quick-action coupling

Design for a pneumatic coupling device

A solar heat collector made up of several metal plates, each bent to provide a first planar portion and a second planar portion at substantially 90.degree., with a flanged hole through each first portion. One or more metal tubes passes through the holes of the plates to position the plates with their second portions forming a substantially continuous sheet. Spacers maintain the plate spacing so that the plate second portions do not overlap. The tubes and flanges are sized so that the tubes are squeezed as they pass through the plate holes, assuring good thermal contact between the tubes and the plates.
