Abstract This invention relates to a block member adapted to secure a cable or wire to a support surface. The block member has a pair of cylindroconical bores with each being adapted to receive a pointed pin therethrough. Each pin has a frustoconical end with an included angle which is less than the included angle of the frustoconical portion of the cylindroconical bore. Around the open end of each bore is an impact absorbing ring. The ring is of the same material as the block member and is adapted to substantially absorb the excess energy that the tool used to drive the pins may contain by crushing on impact. The block member has each bore disposed within a freely depending sleeve to permit the axis of the pin and bore to shift, to a point where the axes could move to thereby permit the pointed end of the pin to avoid a substantially impenetrable object. There are a plurality of recesses in the bottom face of the block including a pair of recesses that are substantially parallel for positioning siamese-type coaxial cable and a recess substantially perpendicular to the parallel recesses for positioning a single coaxial cable. Contemplated by the invention is the concept of the pins being predriven to thereby minimize the need for a high energy impact to secure the block member to a support surface having lesser structural integrity.
A clip for fastening an elongated article onto a support surface made of concrete or like material, comprising a metallic pin and a plastic body portion including a first side adapted to engage said support surface and a second substantially exposed side, a recess formed in said first side completely traversing said first side in a predetermined direction, and at least one cylindroconical bore formed in said plastic body portion at one side of said recess, said cylindroconical bore including a frustoconical portion adjacent said first side, said metallic pin being substantially cylindroconical with a frustoconical end portion and being disposed within said at least one bore, said frustoconical portion of said metallic pin having an included angle less than the included angle of said frustoconical portion of said bore.
