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.

Abstract: A spacer profile (3) has two side pads (8) which are provided permanently with a sealing, plastic and elastic material and comprise continuation pads (11). The continuation pads (11) create, at a distance from their adge area (12) connected to a hollow profile, a first bearing point (13) for the individual plates (2), which is preferably in the form of a spacer or a swelling (15), as well as a clearance (14) located between the continuation pad and the individual plate (2) and filled with the sealing material (9). The continuation pads (11) are elastic and exhibit, in their edge area (12) close to the transverse pad (7), a second bearing point (16), which becomes functional when the side plates (2) are subjected to a load in the transverse direction.
