Abstract: 1. A clamp (1) for connecting form panels which are disposed in coplanar, side-by-side relation and have edge webs (2) or edge sections at least two confronting edges, particularly at all the edges, whereby the clamp has two clamping jaws (4,5) adapted to be urged against the oppositely directed longitudinal faces (3) of the edge webs or edge sections (2) to be fastened together, a carrier (6) connecting the clamping jaws (4,5) and an actuating element for swiveling a first clamping jaw (4), whereby the second clamping jaw (5) is connected to the carrier (6) at a fixed or invariable angle, particularly in a permanent fashion, and the first clamping jaw (4) is slidable relative to, and in the longitudinal direction of, the carrier (6) and in different positions of travel is adapted to swivel about an axis (9) oriented transversely of the carrier (6) by means of a wedge (8), eccentric or similar adjusting element, characterized in that the swiveling first clamping jaw (4) is swivel-mounted on a slide (10) steplessly adjustable relative to the carrier (6) and that the slide (10) is disengageably fixable on the carrier (6) by jamming in any different positions of travel. 2. A clamp as claimed in Claim 1, characterized in that the slide (10) at least partially projects beyond the clamping jaw (4) swivel-mounted on it and does so spaced from the swivel axis (9) so as to form a lever arm, and that an opening (11) for a wedge (8) or a bearing for an eccentric is provided at said projecting area, which wedge (8) or eccentric has the wedge face or eccentric face applied to the swiveling clamping jaw (4). 3. A clamp as claimed in Claim 1 or Claim 2, characterized in that the swiveling clamping jaw (4) takes the form of a double-armed lever whose one arm in the position of use transmits the clamping force and whose other arm, as the actuating arm, projects beyond the swivel bearing (9) to the opposite side, and that the wedge (8) or eccentric is applied to said actuating arm. 4. A clamp as claimed in any one of Claims 1 to 3, characterized in that the slide (10) has a guiding part (101) slidable on the carrier (6), and a holding part (102) capable of swiveling relative to said guiding part (101), which holding part (102) engages over the carrier (6) with an abutment (13) on the side (7) which is remote from the guiding part (101) and is the side on which the clamping jaws (4,5) project from the carrier (6), and that the distance between the guiding part (101) and the abutment (13) which belongs to the holding part (102) and engages over the carrier (6) is greater than the cross-sectional size of the carrier (6) in this direction, so that a swivel movement of the holding part (102) relative to the carrier (6) serves for the abutment (13) to bear clampingly against the carrier (6). 5. A clamp as claimed in any one of the preceding Claims, characterized in that the distance between the swivel axis (9) of the swiveling clamping jaw (4) on the holding portion (102) and the abutment (13) of the adjustable slide (10) is smaller than the distance between the swivel bearing of the slide and the abutment (13), and that the wedge opening (11) or the bearing of the eccentric is provided on the guiding part (101). 6. A clamp as claimed in any one of Claims 1 to 5, characterized in that the wedge (8) is disposed and is movable in an opening (11) with a wedge-shaped taper in the guiding part (101) and that the cross section between the wedge faces of the wedge (8) and the longitudinal expanse of the opening (11) receiving the wedge (8) are oriented approximately parallel to the longitudinal expanse of the carrier (6), in particular outside the outline of the carrier (6) at the carrier hack (12) remote from the clamping jaws (4, 5). 7. A clamp as claimed in any one of Claims 1 to 6, characterized in that the swivel arm of the swiveiling clamping jaw (4) engages over the wedge opening (11) in a fork-like fashion over part of the length and the holding part (102) embraces the carrier (6) on both sides and that the clamping jaw halves are swivel-mounted on the outer surfaces thereof, one to each, whereby the clamping jaw halves are preferably interconnected in a region outside the holding part (102), particularly by way of a crosspiece or cross bolt (14). 8. A clamp as claimed in any one of Claims 1 to 7, characterized in that the carrier (6) has a T-shaped cross section and the T-crosspiece (16) carries the stationary clamping jaw (5) and the swivelling clamping jaw (4) engages over said T-crosspiece, and that guiding part (101) engages the narrow side of 21 the main web (17) of the T-section by means of a groove (18) receiving the edge of the main web (17). 9. A clamp as claimed in any one of Claims 1 to 8, characterized in that the swivel bearing (103) of the holding part (102) is arranged at a preferably open-ended recess (19) of the guiding part (101) and takes the form of a bolt (20) inserted in said recess (19), whereby the recess (19) is open towards the side facing away from the clamping jaws (4, 5) and the bolt (20) extends transversely of and crosses the carrier (6). 10. A clamp as claimed in any one of Claims 1 to characterized in that the travel of the slide (10) or guiding part (101) thereof and/or the movement of the wedge (8) in the open position is limited by a projection (22), an enlarged cross section or the like.
