Claim 3

The block of claim 1 , further including an opening formed through said block from said top surface to said bottom surface of said block.

Claim 4

The block of claim 2 , wherein said opening is located offset between two opposite sides of said block.

Claim 5

The block of claim 2 , wherein said cable channel intersects said opening.

Claim 6

The block of claim 1 , wherein said two sides are parallel to each other, and said two other sides are parallel to each other.

Claim 7

The block of claim 1 , wherein said two sides and said two other sides join at respective four corners of said block, and wherein said corners are formed as a diagonal face with respect to said two sides and said other sides, and wherein said cable channel opens at two opposite diagonal face corners of said block.

Claim 8

The block of claim 6 , further including a second cable channel formed laterally through said block, said second cable channel having openings at opposite diagonal face corners.

Claim 9

The block of claim 7 , wherein said cable channels are formed at different elevations in said block.

Claim 10

The block of claim 1 , wherein no cable channel of said block opens into a female socket member or extends through a male tab member.

Claim 11

The block of claim 1 , wherein said male tab members and said female socket members are formed so to be engaged in an interlocking manner by vertical movement of said block with respect to a neighbor block.

Claim 12

The block of claim 1 , wherein each said male tab member is formed of the same material as a body of said block.

Claim 13

The block of claim 1 , wherein each said cable channel is formed in said block so that a respective cable can be threaded therethrough.

Claim 14

The block of claim 1 , further including a plurality of said blocks interlocked together to form a mat of blocks, and one or more cables threaded through the cable channels of each said block of the mat, said blocks arranged in rows and columns of said mat, and said cables threaded in diagonal paths through said mat.

Claim 15

The mat of blocks of claim 13 , wherein said paths of said cables are linear and at acute angles with respect to the rows and columns of said blocks.

Claim 16

The mat of blocks of claim 13 , wherein said mat defines a first mat, and further including a second mat, said first and second mats being connected together without interlocking said first and second mats using said male tab members and said female socket members.

Claim 17

The block of claim 1 , wherein said block includes two male tab members and two female socket members, said male tab members extending from adjacent sides of said block, and said female socket members formed in adjacent sides of said block.

Claim 18

The block of claim 1 , wherein said block has only one male tab member and only two female socket members.

Claim 19

The block of claim 1 , wherein said cable channel defines a first cable channel, and further including a second cable channel formed laterally through said block, said first and second cable channels located in said block so that an axis of said first cable channel forms an “X” with an axis of said second cable channel.

Claim 20

An erosion control block, comprising: a block formed of a heavy material, and having at least four sides, four corners, and a top surface and a bottom surface, each said corner comprising a diagonal face; at least one side of two sides of said block having formed thereon a respective male tab member extending therefrom, said male tab member including a neck portion and an enlarged end; two other sides of said block having formed therein a respective female socket member, each said female socket member including a narrow opening which opens into a socket, said socket for receiving therein an enlarged end of a male tab member of another similarly-constructed block, each said female socket constructed so that when an enlarged end of a respective male tab member of a neighbor block is received therein, said block and each neighbor block cannot be laterally removed therefrom; an opening formed in said block, said opening extending from said top surface to said bottom surface of said block; and a first cable channel and a second cable channel formed laterally through said block, said first and second cable channels formed as conduits in said block so that respective cables can be threaded through said cable channels after said block and neighbor blocks are interlocked together, said first cable channel opening at one thereof at one said diagonal corner face and at another end thereof at an opposite diagonal corner face of said block, said second cable channel opening at opposite diagonal corner faces of said block, said first and second cable channels located in said block so that an axis of said first cable channel forms an “X” with an axis of said second cable channel.

Claim 21

An erosion control block, comprising: a block formed of a heavy material, and having at least four sides, four corners, and a top surface and a bottom surface, each said corner comprising a diagonal face; at least one side of two sides of said block having formed thereon a respective male tab member extending therefrom, said male tab member including a neck portion and an enlarged end; two other sides of said block having formed therein a respective female socket member, each said female socket member including a narrow opening which opens into a socket, said socket for receiving therein an enlarged end of a male tab member of another similarly-constructed block, each said female socket constructed so that when an enlarged end of a respective male tab member of a neighbor block is received therein, said block and each neighbor block cannot be laterally removed therefrom; an opening formed in said block, said opening extending from said top surface to said bottom surface of said block; and a first cable channel and a second cable channel formed laterally through said block, said first and second cable channels formed as conduits in said block so that respective cables can be threaded through said cable channels after said block and neighbor blocks are interlocked together, said first cable channel opening at one thereof at one said diagonal corner face and at another end thereof at an opposite diagonal corner face of said block, said second cable channel opening at opposite diagonal corner faces of said block, said first and second cable channels located in said block so that an axis of said first cable channel forms an “X” with an axis of said second cable channel.

Claim 22

The block of claim 19 , wherein the axes of said first and second cable channels extend through said opening formed in said block.
