Abstract
A straight connection piece or connector (1) is used to form a spacer frame or spacer for insulated glass panes. The cross-section of the straight connection pieces (1) fits into the inner hollow section of the hollow profile (2) and the shape and contour of the connection piece corresponds to the hollow profile, at least in parts, in order to partially support and reinforce the hollow profile (2) from the inside in the area of the point of insertion. A recess (4) is provided on the back of the connection piece (1) that faces towards the outer transverse crosspiece (3) of the hollow profile (2) in the in-use position, in its central area. The recess extends over both sides of the point of insertion in the hollow profiles (2). The ends of the outer transverse crosspiece (3) of the hollow profile (2) that face each other can be deformed into the recess.
