Abstract
Abstract A plastic clip for securing a panel or like member to a stud or like securement member is disclosed. The clip comprises a first member having a head portion having a through hole and a pair of locking portions extending from the head portion and capable of being pivoted relative to the head portion and a second member having an insertion portion to be inserted through the through hole and a locking portion to be locked to the securement member. By inserting the insertion portion of the second member into the through hole of the first member after insertion of the pair of locking portions of the first member through a mounting hole of the member to be secured, the pair of locking portions are pivoted away from each other so as to clamp the member to be secured. In this state, the locking portion of the second member is secured to the securement member, thus securing the member to be secured to the securement member.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
288 words
A clip for securing a member to a stud or similar support member, comprising: a first member having a head portion for engagement with a first surface of said member to be secured; a through-hole defined within said head portion; radially outwardly expansible locking portions operatively connected to said head portion and engageable with a second surface of said member to be secured when moved to a radially outwardly expanded position so as to cooperate with said head portion whereby said member to be secured is clampingly engaged between said head portion and said locking portions; and first locking means defined upon said locking portions; and a second member comprising an insertion portion to be inserted through said through-hole of said head portion of said first member so as to engage said locking portions of said first member and thereby move said locking portions to said radially outwardly expanded position; second locking means defined upon said insertion portion of said second member for lockingly engaging said first locking means of said locking portions of said first member when said insertion portion has been inserted through said through-hole of said head portion of said first member and has engaged said locking portions of said first member so as to move said locking portions to said expanded position, whereby said member to be secured will be lockingly clamped between said head and locking portions of said first member and said first and second members will be locked together; and bore means defined within an end portion of said insertion portion for lockingly receiving said stud-type support member whereby said clip, comprising said first and second members, is able to secure said member to be secured to said stud-type support member.
Claim 2
Dependent Claim
288 words
A clip for securing a member to a stud or similar support member, comprising: a first member having a head portion for engagement with a first surface of said member to be secured; a through-hole defined within said head portion; radially outwardly expansible locking portions operatively connected to said head portion and engageable with a second surface of said member to be secured when moved to a radially outwardly expanded position so as to cooperate with said head portion whereby said member to be secured is clampingly engaged between said head portion and said locking portions; and first locking means defined upon said locking portions; and a second member comprising an insertion portion to be inserted through said through-hole of said head portion of said first member so as to engage said locking portions of said first member and thereby move said locking portions to said radially outwardly expanded position; second locking means defined upon said insertion portion of said second member for lockingly engaging said first locking means of said locking portions of said first member when said insertion portion has been inserted through said through-hole of said head portion of said first member and has engaged said locking portions of said first member so as to move said locking portions to said expanded position, whereby said member to be secured will be lockingly clamped between said head and locking portions of said first member and said first and second members will be locked together; and bore means defined within an end portion of said insertion portion for lockingly receiving said stud-type support member whereby said clip, comprising said first and second members, is able to secure said member to be secured to said stud-type support member.
