[0024] Reference Figures 1 to 7, the strap assembly 10 may include a strap 12 having a buckle 11, and the buckle 11 is fixed to the proximal end 13 of the strap 12. When in use, the strap 12 is connected into a ring shape to play a fastening effect.

[0025] The strip 12 may be formed of a resilient material, such as an elastomer. The strip 12 has a distal end 14 which may taper toward a tip and is longitudinally opposite the proximal end 13 and has a substantially constant width and thickness over its entire length. A plurality of holes 15 passing through the thickness of the strip 12 are longitudinally arranged at regular intervals P. The holes may be longitudinally elongated or oblong or elliptical. The proximal end 13 terminates in an enlarged head 16 integral with the strip 12. Offset from the enlarged head 16 are transverse ribs 17.

[0026] A slot 20 at a longitudinal end of the buckle 11 receives the proximal end 13, an enlarged head 16 secures the proximal end 13 to prevent it from separating under tension, and a transverse rib 17 holds the strap 12 when not under tension. The buckle 11 is a one-piece piece having an inner side 18 and an opposing outer side 19. A pair of prongs 21a, 21b protrude from the outer side 19, the prongs 21a, 21b being arranged relative to each other to be aligned with the longitudinal axis 22 and configured to be simultaneously received in the corresponding holes 15. The prongs 21a, 21b may protrude from a longitudinally elongated generally flat surface 23 and may be parallel to each other and inclined at an acute angle relative to the generally flat surface 23.

[0027] The abutment surface 24 on the inner side 18 is used to abut against a complementary surface of the item to be fastened, particularly the panel 25. The panel 25 can be generally flat and have a honeycomb pattern of nested hexagonal openings 30. The abutment surface 24 can extend around the perimeter of the buckle 11.

[0028] The protrusion 26 on the inner side 18 may be generally sleeve-shaped with axial slits 27, 28 to reduce stiffness. The abutment surface 24 may extend around the protrusion 26 so that the free end 29 of the protrusion 26 is located outside the abutment surface 24. The free end 29 includes an outwardly turned lip 31. In this way, the protrusion 26 is adapted to be received in one of the hexagonal openings 30 of the panel 25, and the reception of the protrusion 26 in the opening 30 causes the protrusion 26 to be elastically deformed to provide a snap fastening for connecting the buckle 11 to the panel 25.

[0029] The buckle may also include a pair of ribs 32 that are longitudinally elongated parallel to the strap 12, the ribs 32 having outer edges 33 on the outer side 19, the outer edges 33 defining therebetween a mouth 34a of a strap receiving channel 34 in which the prongs 21a, 21b are located. In use, when a loop is formed to secure the strap assembly 10, the strap 12 is received in the strap receiving channel 34. The prongs 21a, 21b may be recessed to protect within imaginary boundary planes 36, 37 that define the boundaries of the strap receiving channel 34 and intersect the outer edges 33.

[0030] A corresponding tongue 35 may extend transversely from each outer edge 33. The tongues 35 may extend relative to and toward each other to locally reduce the width of the mouth 34a to a size less than the width of the strip 12. The tongues 35 are longitudinally spaced from the prongs 21a, 21b. In this way, by deforming the strip 12, the strip 12 may pass between the tongues 35, and the tongues 35 tend to retain the strip 12 in the channel 34.

[0031] Aspects of the present invention have been described by way of example only, and it should be appreciated that modifications and additions may be made thereto without departing from the scope thereof.
