The walls are flexible and the edges of the slot grip and support the edge of the sheet of material once inserted into the slot.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
A jointing member of hollow cylindrical form having at least one internal compartment extending lengthwise of the member part of the surface of the member forming an outer wall of the internal compartment, said outer wall being slit longitudinally of the member to divide the wall into two lips whose edges are in contact, the lips being of a resilient material and thereby deformable to allow entry into the compartment of the edge of a sheet of material which is then retained in position by said resilient lips.
Claim 2
Dependent Claim
88 words
A jointing member of hollow cylindrical form having at least one internal compartment extending lengthwise of the member part of the surface of the member forming an outer wall of the internal compartment, said outer wall being slit longitudinally of the member to divide the wall into two lips whose edges are in contact, the lips being of a resilient material and thereby deformable to allow entry into the compartment of the edge of a sheet of material which is then retained in position by said resilient lips.
Claim 3
Dependent Claim
18 words
A jointing member as claimed in claim 1 in which said edges are contoured to provide inter-meshing surfaces.
Claim 4
Dependent Claim
19 words
A jointing member as claimed in claim 1 in which said edges incorporate a tongue and groove type connection.
Claim 5
Dependent Claim
22 words
A jointing member as claimed in claim 1 in which the edges of the said wall parts are corrugated, the corrugations inter-meshing.
Claim 6
Dependent Claim
51 words
A jointing member as claimed in claim 1 in which the member has at least one internal wall which defines, in part said internal compartment, said internal wall extending over part only of the length of the member, there being an end portion of said member that is not divided internally.
Claim 7
Dependent Claim
21 words
A jointing member as claimed in claim 5 in which said member has two end portions that are not divided internally.
Claim 8
Dependent Claim
32 words
An assembly as claimed in claim 5 and further comprising a connecting member located in the end portion of one jointing member and partly in the end portion of another jointing member.
Claim 9
Dependent Claim
91 words
A jointing member as claimed in claim 1 and further including a plurality of internal walls that divide said member into several longitudinally-extending hollow compartments, each said compartment having an outer wall with a slit that extends longitudinally of the member and divide said outer wall into two parts whose edges are in contact, said parts being of a resilient material whereby said parts are deformable to allow entry into said slot of a sheet of material which is then retained in said slot by said resilient parts of said wall.
Claim 10
Dependent Claim
53 words
An assembly comprising at least two jointing members as claimed in claim 8, the jointing members being so arranged that the hollow compartments therein are aligned one with another, and a connecting member located partly within a compartment of one supporting member and partly within the aligned compartment of the other supporting member.
Claim 11
Dependent Claim
29 words
An assembly as claimed in claim 7 in which the connecting member has a peripheral flange between its ends, the flange abutting adjacent ends of the two jointing members.
