Abstract: A preferably straight plug connector (1) is provided for hollow profiles (23), in particular warm edge hollow profiles, of spacers of insulation glazing. The plug connector (1) has a substantially U-shaped cross-section with open end faces (26) and a base (2) facing the pane inner space when installed, and has side walls (3) along its edges and a centering aid (24). Laterally flared resilient retaining elements (6, 7, 8, 9), which have a straight lower edge (11) in the side view, are mounted on the free edge (4) of the side walls (3).

Abstract: A plug connector (1) and a plug connection (2), for hollow profiled sections (3, 4) of spacers of an insulating glazing, has a base (8) with edge-side lateral walls (10), a central stop (21), and retaining elements (16). The plug connector (1) is formed of a temperature-resistant material, in particular metal, at least in the region of the connector center (20) and is suitable for a welding connection (5) of the hollow profiled sections (3, 4). The plug connector has a shape which is rigid against external transverse loads at least in the central region and a substantially U-shaped cross-section with a hammerhead shape and lateral walls (10), which are recessed in steps (11) in the upper region (12). The lateral walls (10) have a supporting and retaining structure (15), which is oriented towards the roof (27) of the hollow profiled sections (3, 4), at the upper free edge (14).

Abstract: A plug-in connector (1), for warm edge hollow profiles (2) of spacers of insulating glazing, has a base with side walls (6) at the edges. A plurality of retaining elements (15) formed as spring lugs are arranged on the outer side of the base (bottom) (5) in a single central row on each of both sides of the center (3) of the plug-in connector (1). Starting from the base (5), the retaining elements are directed obliquely outwards towards the adjacent hollow profile base (28) and towards the connector center (3). The retaining elements (15) are in each case arranged in a sunken base region (13) on the outer side of the base (5) that adjoins a raised, plate-like base region (11) arranged in the region of the center (3). Laterally obliquely outwardly directed resilient retaining elements (18,19) are arranged at the free edge region (7) of the side walls (6).

Abstract: A straight connector (1), for hollow profiled elements (2) of spacer frames, mullions, or transoms for insulated glass panes, has several connector legs (6, 7) extending in various directions from a central connection point (9). The connector legs have retaining elements (18) for engaging on a hollow profiled element (2). The straight connector (1) has a base plate (10), with a top side with a raised support base (12) for the hollow profiled elements (2) and on both sides thereof on the connector legs (6, 7) the fin-like retaining elements (18) are arranged one after the other in a row. The support base (12) is arranged, in a longitudinal direction, in the center and has a center stop (8) for the hollow profiled elements to be put on, on both sides and which hollow profiled elements are supported at the joint (26) by the support base.

Abstract: An insertion connector (1) is provided for hollow profiled elements (17, 18) of spacers or mullions for insulating glass panes. The insertion connector includes lateral walls (3) and at least one central wall (2) having at least one long opening (9) extending along the longitudinal axis 23) of the connector. At least one holding element (7) projects from the central wall (2). The holding element (7) is arranged adjacently to the through-opening (9). The insertion connector (1) can include other holding elements on the lateral walls (3).

Abstract: A plug-in connection (1) is provided for hollow profiled elements (2) of spacer holding frames for insulating glass panes. The plug-in connector (1) has at least one connector part (3, 4) including an essentially U-shaped or box-type cross-section, having lateral walls (15, 16), at least one central wall (14), and, on the connection point (8), a central abutment (18) with a plurality of elastic abutment elements (19, 20), on the edge region of the lateral walls (15, 16). The central abutment includes two mutually oriented individual abutment elements (19, 20) which are arranged on both sides of the connection point (8), each on a lateral wall (15, 16), and have a cushioning effect essentially in the plane of the associated lateral wall (15, 16) thereof. The lateral wall (15, 16) have a recess (26) beneath the abutment element (19, 20).

Abstract: The invention relates to a plug connector (1) for hollow profiles (4) in spacer frames for insulated glass panes. The plug connector (1) comprises at least two connector parts (2, 3) which may be plugged together and which have an essentially U-shaped or rectangular cross-section, which, in the plugged position, have adjacent side walls (6,17) and a positive fit (9). One connector part (2) has at least one retainer element (12) on the side walls (6) thereof (12) with a corresponding wall opening (13). In order to form the positive connection (9), the other connector part (3) has a projection (10) with a positive fit engagement in the wall opening (13) of the retainer element (12) when in the plugged position.
