An anchor and an attachment base assembly comprises a base having at least one base aperture, and an anchor selectively operatively connected to the base. The anchor is selectively inserted at least partially into the at least one base aperture and optionally into an aperture of an accessory. The anchor has a base part movable between a locked position where the anchor is secured to the base and an unlocked position where the anchor is free from the base. An accessory part is operatively connected to the base part. The accessory part is adapted to selectively connect at least partially to a brim of the aperture of the accessory for bracing at least partially the accessory to the base when the anchor is in the locked position. The anchor has other features. A vehicle having an anchor and an attachment base assembly is also presented.
