Definitions

• the invention relates to a fastening clamp for trapezoidal ropes for their attachment to the boom of a windsurfing rig, with the features of the preamble of claim 1.
• Such a fastening clamp is known from DE-GM 88 05 546 in a form in which the means for releasing the
• Buckle to prevent unintentional unhinging consist of a kind of trap with a ring that can be attached to the shell, which prevents the locking lever from being pivoted fully into its release position in the suspended state. This is to ensure that the buckle can be detached to such an extent that the fastening clamp on the boom can be moved without having to leave the boom. Quite apart from the fact that the trap in question can hardly function in the manner indicated in the attachment and dimensioning shown, because the freedom of movement of the locking lever is much too small for this, such a trap is complex and impractical. In addition, it forms an undesirably protruding part of the fastening clamp protruding from the shell, which can lead to painful pressure points and blisters on the surfer's hand.
• the invention has for its object to provide a fastening clamp of the type referred to in the generic type simpler, easier to use and non-disruptive protruding means to prevent complete release of the fastening clamp, which nonetheless make it possible to easily, even during, the fastening clamp of use and with just one hand.
• This object is achieved according to the invention by the characterizing features of claim 1.
• the subclaims also indicate advantageous design options.
• the pre-tensioning force that can be produced in the manufacture of the shell solely by appropriate non-round shaping prevents the fastening clamp from opening fully and in this way leaving the boom tube, while on the other hand the buckle can be fully opened in order to allow the shell to be expanded as much as possible.
• the aforementioned pretensioning force causes the shell to expand on its own and is therefore easy to move when the buckle is open. A complete opening of the clamp while unhooking the buckle is, however, easily possible by compressing the shell while overcoming its pretension.

• Fig. 2 shows a cross section through the same fastening clamp in the plane of line II-II of Fig. 1 and
• Fig. 3 shows the same cross-section with the buckle attached but open.
• the fastening clamp shown has a clasp-like shell 2 made of a tough elastic plastic, which is suitable for enclosing a boom tube 4, as indicated by dashed lines in FIGS. 2 and 3, at an angle of more than 270.
• the shell 2 has ends 6 and 8 which are reinforced in the circumferential direction.
• a locking lever 14 is in a recess 10 in the shell end 6 by means of transverse bearing bolts 12 a two-part buckle 16 pivotally mounted, which can be folded into a closed position substantially within the recess 10, from which it only protrudes slightly at its free end to the outside.
• a connecting member 22 is pivotally mounted by means of a transverse bearing bolt 20, which disappears in the recess 18 over part of its length in the closed position of the buckle and finds a stop in a shoulder 24 on the recess 18, which on
• the connecting member 22 has pins 26 on both sides formed by an inserted bolt, with which it can engage in a groove 28 interrupted in the middle within the shell end 8.
• the groove 28 has a profile which is inclined radially outwards from the opposite shell end 6. In this way, the buckle 16, more precisely the connecting member 22, can be swiveled into the narrow scarf 8.
• the shell 2 tapers away from the two shell ends 6 and 8, with the exception of a radially outwardly pointing eye 30 for receiving the trapezoidal tamping, in order to form a relatively thin, elastically deformable wall 34 in its central region 32.
• the shell 2 is produced with a somewhat non-circular profile, due to which it has a pretension that spreads the two shell ends 6 and 8 apart with respect to the circular boom tube 4.
• This pretensioning means that the connecting member 22, once hooked into the groove 28 of the shell end 8, cannot easily leave the groove 28 again even when the buckle 16 is open.
