Abstract: A device and a method for fastening a first object of a second object are provided. The device comprises a sleeve and an arbor, wherein the sleeve comprises a first load application means for the first object and an abutment for an outer surface of the second object, as well as a passage, wherein a contraction of the passage in the sleeve extends at least up to the point of the passage that is the closest adjacent point to the abutment.

Abstract: A grid holding element has a first leg (11) at least one free end of which is hook-shaped, and a second leg (12) having a saddle-shaped attachment section (20) in which a through-opening (23) through which a fastening element (30) is extendable, is formed, a first foot section (2) that projects from the attachment section in a direction away from the first leg (11), and a second foot section (22) adjoining the first leg (11), with a maximal extension length (D1) of the first foot section (21) in a direction perpendicular to a plane (E) defined by the attachment section (20), being greater than a maximal extension length (D2) of the second foot section (22) in the direction perpendicular to the plane (E).

Abstract: A fastening element having a stem (11) with a tip (12) provided at one of its ends, a head (13) provided at another opposite end, and a guide cylindrical member (30) mounted on the stem (11) for guiding the fastening element (10) in a bolt guide (40) of a setting tool, and having a retaining section (33) for retaining a washer (20).

Abstract: A holding element for securing gratings (50) to supports (40) includes first leg-shaped engagement part (11), a second engagement part (12), and a connection section for connecting the first (11) and the second (12) engagement parts, with the first and second engagement parts (11, 12) projecting from the connection section and being spaced from each other along a longitudinal axis (L) of the connection section, and with the connection section being formed, at least partially, of a spring element (13) elastically expandable in a direction of the longitudinal axis (L) of the connection section by up to 150% of its initial length (A).

Abstract: A holding element for securing gratings (50) on supports (40) includes a leg-shaped first engagement part (11), a second engagement part (12), screw (30) for securing the first and second engagement parts (11, 12) with each other along a clamping axis (A), and an elongate guide element (13) spaced from the clamping axis (A), securable to one of the first and second parts (12) and displaceable in an opening (20) formed in another of the first and second parts (11).

Abstract: A holding element for a grating has a first leg (11) at least one free end of which is hook-shaped and a second leg (12) having an attachment section (20) provided with a through-opening (23) for a fastening element (60). The first leg section includes a first leg section (14) carrying the hook-shaped end (13), a second leg section (15) along which the first leg section (14) is telescopically displaceable in a longitudinal direction (L) of the first leg (11), and a locking mechanism (30) provided between the first leg section (14) and the second leg section (15) for retaining the first leg section (14) on the second leg section (15).

Abstract: A fastening element having a stem (11) with a tip (12) provided at one of its ends, a head (13) provided at another opposite end, and a guide cylindrical member (30) mounted on the stem (11) for guiding the fastening element (10) in a bolt guide (40) of a setting tool, and having a retaining section (33) for retaining a washer (20).

Abstract: A grid holding element has a first leg (11) at least one free end of which is hook-shaped, and a second leg (12) having a saddle-shaped attachment section (20) in which a through-opening (23) through which a fastening element (30) is extendable, is formed, a first foot section (2) that projects from the attachment section in a direction away from the first leg (11), and a second foot section (22) adjoining the first leg (11), with a maximal extension length (D1) of the first foot section (21) in a direction perpendicular to a plane (E) defined by the attachment section (20), being greater than a maximal extension length (D2) of the second foot section (22) in the direction perpendicular to the plane (E).

Abstract: A nail-shaped fastening element including a first, conical section (1, 11 21) tapering in a setting direction of the fastening element and having a shaped surface profile extending at least along a portion of the first section, and a second section (2, 12, 22) adjoining the first section (1, 11, 21) at end of the first section remote from the fastening element tip (5, 15, 25).

Abstract: A holding element for tubular objects has a holding member (11); and an attachment member (20) with an abutment (22) for a fastening element (30), which extends through a through-opening (21) formed in the attachment member (20), with the attachment member (20) further including at least two spring shackles (23, 24) provided sidewise of the abutment (22) and each having a retaining section (28) provided on its outer surface for friction-lockingly and/or force-lockingly temporary securing the holding element (10) on a bolt guide (40) of a setting tool.
