ANCHORING DEVICE
An anchoring device (1) for a guideline having the form of an elongated body with a bottom anchoring assembly (1a) furnished with spring-loaded retractable (5) locking arms (4) and a top, line-attachment assembly (1b) for the guideline, arranged so as to provide for anchoring to a guidepost, wherein the anchoring assembly (1a) and line-attachment assembly (1b) are held together in anchoring mode by a shear pin (12). The anchoring assembly comprises a barrel piece (7) which is telescopically displaceable relative to a central core (9) fastened to the guideline-attachment assembly (1b), whereby the barrel piece (7) upon shearing of the shear pin (12) is telescopically displaced downward relative to the central core (9) of the anchoring assembly (1a), and wherein said central core (9) and locking arms (4) are furnished with adjacent and collaborating guide surfaces (9b, 4a) which upon downward displacement of the barrel piece (7) are caused to interact with each other and bring about the retraction of the locking arms into their non-locking position.
