An anchor member for mounting a tarpaulin to a bearing structure includes: a shaft; an obliquely arranged transverse pin located at a first end of the shaft; a rod member protruding from the shaft and having a first hook-shaped protrusion at an end thereof; and a double hook located at a second end of the shaft. The double hook includes two hook arms positioned on opposite sides of the shaft, and each of the hook arms has an opening. One hook arm includes a second hook-shaped protrusion that engages the first hook-shaped protrusion of the rod member to thereby form a spring lock that completely closes the opening of the first hook arm. In use, an elastic band connects the anchor member with a bearing construction, wherein the elastic band, when mounted, is received in the openings of the hook arms of the anchor member.

An anchoring eyelet for tarpaulins and similar coverings of a thermoplastic foil material is designed as a substantially annular disc (1) made of plastic. The eyelet has an eyelet opening (2) and is designed in its peripheral part with increased resiliency by means of indentations which may be formed by radially extending resilient tongues (3) or lobes. This avoids any tendency of the eyelets to become detached after being pressed in, while forming notches at heavy loads.
